I have a 1985 IROC-Z I just got a new GM creat motor for it.The motor is the 350/330hp I would like to put a set of headers on it.The headers that I'm looking at are the SLP's,Hookers,Edelbrock
and the Hedman headers.Or any other one's that would work better for.Thanks for your HELP!?!?!?

 

i dont have headers but if i got some id probably go SLP, a lot of guys have em and seem to get some good results.

 

Got the same crate....CONGRATS!!! I am using hooker super comp shorties 1 5/8" tubes. I had the AIR tubes cut and holes welded shut (no emissions ). I have had NO PROBLEM with 'em. Are you keeping the TPI or going with the carb??

Later

Oh yeah...click the link below to see the motor in the car!!

 

Yes I'm keeping the TPI for the motor.I'm getting the SLP Runners for it they should be here very soon.When I get it in I will put them on my web page.When you can check out my page

Only considering shorties: SLP's are the best, Hookers (imo) are the best overall value.

 

i have a pair of the edelbrock tubular headers and they work great i paid about $330 and it came with everything i needed!

 

I have the Edelbrock TES, they work and sound great, they were an easy install as far as headers go. but the choice is yours!!

 

SLP headers are the best. I got Edelbrock and hated them. That and Accel Superram intakes. and a custom EPROM to maximize your system.

 

I had 1"3/4 slp and hated them ,they did still look nice after they were heated up a few times,but the problems weren't worth the nice look.I had to change the motor mounts because the headers hit the sterring linkage.Then the heat caused my fuel to boil and vapor lock,and this was after wrapping the headers and the fuel line on the drivers side.This is with 1"3/4 and on a 89 gta trans am .I never used the 1"5/8 ,maybe fitment would be better?? I have edelbrock now and they installed very easily,and i've been happy with them.They do look kinda krappy now that the paint's burned off so i might get them ceramic coated or just wrap em
Hope this helps

 

Are 1"5/8 a good size for headers?

 

In my opinion if your under 400 horsepower, use 1"5/8.

 

Hedman makes the 1 5/8" primaries and 3in y pipe to match for our cars for $225 shipped from jegs

i have a set on my 90 RS and i set on my IROC and i love them

soon to get a 383 and some hooker supercomps but that is later,

 

actualy... i want an 3-inch exhaust... what model u have for ur ROC?

 

I have the SLP 3 in exhaust and am quite happy with it. Fit well.
