Is there any problems with clearence using shorty headers? How close do they run to the starter? They're gonna go on an 86 Z-28. 305 TPI. Thanks for any help!

What brand are you talking about? I would also see what I planned for the car. If I was going with a 383 later, I would get 1 3/4 primary tube SLP. If not, I would go 1 5/8 SLP.

I had no problem with my 84, 305ci.
When I went to the 383 and LT's I had to put one of the small high torque starters in.

P.S. Was a little close, so I use a starter heat shield.

i wouldnt buy SLP headers if i had the choice. from what ive heard they make it real hard to get to the plugs and stuff like that. i have heddman shorties on mine and they fit so easy and i can see almost all the plugs. i can change the plugs ALOT easier w/ these headers on than w/ the stock manifolds. and the best part besides fitting so good....they were the cheap in price.

I have SLP 1 3/4 headers and it's easier to change plugs than with stock stuff. I can do it all from the top now. You will need to cut ~.75" off a 14mm plug socket and use I believe a 3/4' ratchet wrench on the back of the socket but, you can see as well as access all 8 plugs.

youre insane i have slps on my car and they are a nightmare they run so damn close its really hard to get at the plugs....very do able but not easy....anyways theyre good if you have clearence issues otherwies id go heddman

I don't have the smog pump which makes a little diference but I don't have a problem with doing the plugs. Easier than stock manifolds.

I went with Edelbrock TES headers and then had to go with a mini-starter because of heat soak. I have room to change the plugs as long as I do the passenger side from underneath.

Do any of you Heddman guys have flange warpage problems? I had a set and two of my buddies have them right now, and it is constantlly time to put in new header gaskets. Their cheesy flange is worthless, my buddies '88 GTA on the other hand is running SLP's and they are a far superior product. Another buddy has the Edelbrocks and they are kind of middle of the road. You get what you pay for.

I have the SLP's 1 3/4ths and routed most of the plug wires from the top.. with about 3-4 of those bundling clips.. they were all easy to put in.. the middle two on the driver side had to use a special wrench on them because was no way able to get a socket on them.. and the the back two on the passenger side i had to get under the car to push on.. I have all the stock AIR and stuff too. Passenger side header was put on when engine was not put in yet.. driver side header i unbolted the driver side engine mount and jacked up the engine about 1/4-1/2 inch and it dropped right in.. Definitly a good set of headers.

oh yea.. alrighty was planning on a ministarter.. so thats what i used.. Ministarter a lot easier to get up there without droppin the exhaust too.. which is a little bit bigger with headers going to a 3" Y

If you can get away with it this is how it's done

doug791 no not insane. I just have a can do attitude. Granted it's not like changing plugs on a 69 Chevy with an inline 6 but I have no trouble reaching the plugs from the top. As alkim said, I also removed the un-neccessary smog pump.

aklim

I don't know about the "special" socket that SLP sells for it either. Always wanted to get one just to see but never needed it. Acutally, it took 5 hours the last time because some friends came over and had a case of beer.

Yeah, thats great if you can remove all emissions
related components, but which headers are the easiest to work with when your engine has to be "as is" from the factory?

I think most people with the Hooker shorty heads will tell you that they work very well. No problem reaching the plugs, putting on the boots or bumping into the steering column.

SLP headers are NOTORIOUS for not fitting around the steering column.

Here is a useful tip: use Bosch Platinum single prong plugs. They are shorter than average and leave just enough room for the rubber spark plug boot to not press against the header. They also last 2 or 3 times longer than your average AC plug, meaning you only have to do the nasty spark plug removal scene every third year or so

Mine fit around the steering column just fine. No fiddling. In any case, the smog pump just makes #2 and #4 a little more difficult. Go from down below and you should have no problems. That or take the smog pump diverters off when you do it. Just a couple of 10mm bolts. I am using NGK V power plugs with Accel 300+ wires and no problems of burning boots.
