I was thinking about this for a few reasons.

1) I will we going to 1.6 RR's and need to put new springs on.
2) Need to fix Intake manifold leak
3) I'm very leery of doing the cam and then spinning some bearings (I know its not a certain thing, but I've seen the posts and know someone who has done it)

I figure the intake will be off, and it will be a lot easier to pull the heads to do springs, might as well spend like 1K on some ported heads, and then sell mine for $200.

Be sure to get 95 or earlier heads.They are better for porting. You won't notice much of a gain, maybe 25rwhp or 30rwhp as opposed to to 110rwhp-120rwhp the LE2 package would add.

Is it really that much with the package? Thats nice! When I get moved in a few months and get my garage, I want to start building a decent short block, so eventually I could put the heads on that with no worries.

Well with bolt ons you will get from 400-420 rwhp. So assuming bolts ons take you to 290-300rwhp it will be about 110-130rwhp increase. I am getting the 1.5 Setup which is only $1400 he uses different valves than the $1600 package.

Here's like all of the informations about his setups along with a FAQ i made... lol

It's a pretty expensive way to make HP, but it is safer than a cam swap.

There was a post just a little while back where a guy made somewhere around 320 rwhp with just heads and bolt-ons, through an A4, so that's more like 335 rwhp for a M6. http://web.camaross.com/forums/showthread.php?t=321067

I've considered it myself.

le heads come with new springs. just get some nice rockers and set of new lifters if you want and your set.

Thats what I was thinking....

I did just the heads on mine and was happy with the results, Then when I did the stroker I added the cam. Just make sure you know what your long term goal is and have the heads ported toward that goal

changing the heads are want cuases you to spin a bearing not swaping the cam. the heads are what torqe the block and when you pull the heads and put the new ones on you are not going to torqe that block to the exact same place.

so if you giong to do it do the heads right put good springs on it. not lt4s. find what cam you wish to run and put those springs on. then you can just put the cam in later, and not have to buy new springs and install them.

do it right the first time.

So I guess all those guys who have spun bearings, on STOCK unremoved heads, are a figment of our imagination?

That is the most insane thing I've read here in a LONG time. I hope to stop laughing before I get to the shop tomorrow and have to do some work.

That is one of the theories as to explain spun bearings after engine work. Personally I feel that if the block is tweaked that much by torquing the heads then new bearings will do nothing without an alignhone too. Personally it is my opinion that the majority of spun bearings after engine work are due to dirt, nicking a bearing sliding the cam in or out, the too thin oils everyone uses, or mistake use of cam lube it has no place on a roller cam.

OK, can LE port any heads for LT1's, even if they have some mild porting work on them already? I am asking because I just bought a pair of ported heads from a '93 LT-1 that flow 1 cfm less than the LT4 heads on EBay for $400. I also wonder if his work and cam would make it better.

Antz97ZNJ

Cam isnt all that expensive...if you have enough to do heads it wont cost much more for a cam...and if not save longer

ShawnMacAnanny

Yes lloyd can port any heads unles they were screwed up IE the guy punched through a water jacket. He even ports aftermarket heads. His LE heads flow 270/190, Lt4 heads flow 250/170 right?
