Your post does little to discredit SpeedDemon or his results. Taking a shot at an individual by searching their posting history is an interesting tactic. However most of the posts were taken from what I assume is the time period right after he discovered the issue. When a problem is unfolding, it is human nature to search and grab for answers. How many times have people on this board had a "miss" and claimed it was everything from a clutch to an opti? And then replaced it all only to find out it was something all together different?

Throwing his posting history out there during the time of the problem doesn't show anything. Multiple sources found the cause of the issue to be one thing (bad machining etc) and early in his prediciment he thought it was something totally different. That isn't his fault, it is hind sight.

which part - the professional scammer issue or other valvetrain issues?

Bret had quite the history on this board. I wasn't trying to be a dick, just breifly highlighting some of the issues people had with Bret during his time on the board.

This thread is not about him or his history, it is about one persons results with a product. I would love to go into it further, but this is neither the time nor the place.

For the Bret issue, please see JasonD's post in regard to the matter.

Let's not carry it any further than that in this thread.

Thought I had read every thread detailing sd's ongoing misadventures and this is the first I have seen of it as well.

I can tell you guys my results and take them as you will, Lloyd ported my first set of heads for me back in 2003 or so and I have only gone faster since with his portwork, which picked my car from 12.00@113mph (stock heads) to 11.61@117mph, same heads, same valves, same cam (LE1), same everything. I removed the heads sent them to Lloyd then reinstalled the heads and ran .4 tenths faster and 4mph on the first nite out. I then sprayed 150HP n2o and broke some main bearing caps (detonation) so I never got to really dial in that setup that would have easily run 11.40's with some tweaking. vbut i went with some LE2's and bigger cam 11.20@120mph and on n2o 10.20@132mph So his porting definately makes HP and stuff breaks in the high performance world no matter who you are.

I too, am on this site pretty often and have never heard mention that these heads had already been worked on. Why is this just now coming out?And tireburnin, this is your attempt at letting both sides tell their story? Professional scammer?

Javier97Z28

This post where he gives his before/after numbers should be a giveaway that work was not started on a "stock" head.

On a side note, if it was felt the heads were not good enough to be ported to a good result, I don't think they should have been used and Rob should have been told to look for an untouched casting. Just IMO.

This is not a Lloyd bash as I obviously run his product and my car has performed well with it.

The point was that it is not mentioned in the Lloyd-bashing threads.

Most people who have followed the saga as it has unfolded probably didn't go back to read all the relevant threads that SD posted prior to having problems.

I agree. Had the heads been unworkable, Lloyd wouldn't have touched them. If I remember correctly Robert always used to tout the "mild ported" heads before switching to the LE setup. He was happy with the mild heads but sent them out to be ported to LE2 specs and gained 30 cfm. I believe he posted the before pictures and results and after of that setup vs. LE.

Now how do you go from mild ported (bowl work) to 218cc? If the runner was say 19Xcc from the previous porter, there should have been plenty of room to get to the desired 205cc. Is this were CNC porting shows its true benefit? A cnc machine would never hog out a port to 217.X on one and 216.X on another.

dangalla

the cnc would have done the same thing lloyd did, and it still would have turned out the same due to the previous porting in areas that neither would have touched

it was already posted, but you obviously only read what you want

Z-RATED94

tireburnin, do you read the stuff you type? Do you know how a cnc machine works? Have you ever heard of altering some of the ports that would be lacking in the first place? And granted, not that this would apply in all cases.
A cnc head is nothing more than a copy. Oh wait, I'm off by
1 cc, let me go back and fix that.

When I sent the heads to you you said they were fine for porting and none of the previous porting would affect how they turned out. Now you are saying they were butchered and affected the final outcome? It's funny how the "butchered" heads I had before with stock valves outran your LE2 heads and traped 3mph higher than your average le2 setup.

See the quote above. He told me the heads were fine for porting and that the previous porting wouldn't affect the final outcome of the heads.

I went 12.1@118.3mph with my old heads before I sent them to you that flowed ~240cfm according to you in POSITIVE 500 foot d/a. After I got them back from you I went 12.09@118.1 in NEGATIVE 1000 foot d/a. And the guideplates were just starting to wear, and the valves that had the worste guides had the guideplates that had no signes of wear on them. I bought the trickflow guideplates at your reccomendation but now according to you the valve spacing with the gm/trickflow guideplates can cause valveguide wear but you still reccomend the trickflows to your customers. And I had 2 seperate shops check out the heads so even if the 1st one was advanced induction (which it wasn't) that would still leave another shop out there. One of the places is a sponsor on LS1tech so I'm not going to say who they are out of respect for them.

I never said they were worn badly. They I said they were just starting to show signs of wear, and like I previously said the guides with the worst slop/wear had the guideplates that had no signs of wear on them at all.

Yeah they gained 30rwhp over my old setup but slowed my car down at the track. Dyno queen FTL. And I'm 99% sure I broke that plug taking it off with the side load on the socket. I was just looking for an excuse to why my car didn't gain anything after I got the heads back from you. I checked for arcing on my wires/coil/plugs to see if that was a problem but it wasn't, and I would think a broken spark plug would be arcing pretty bad.

speed_demon24

I never hid the fact that they were previously ported. I just never made it a priority to point it out since Lloyd told me it would have zero affect on the final outcome of the LE2 heads.

speed_demon24

Just out of curiosity Lloyd, what is your excuse that the vavlespring installed height varied from 1.75-1.80" on your LE2 heads when I checked it? Shouldn't it all be installed at the same height, expecially since the cam I was running had the most aggressive hydrolic roller lobes comp sells? Even more aggressive than the LSK LSx lobes that bret bashes and the XFI lobes that he also bashes since they are so "aggressive"? My 224 cam had more duration at .200" lift than the cc306 by almost 10 degrees.

I guess I was lucky that I pulled the motor apart before the lobe started coming apart. The valvefloat only took out the rollers on a few of my lifters... I've also gotten numerous PM's from members on this board since they are having similar problems.
