I have hooker headers on mine. when I ran them with my stock heads they fit better than any other headers I have had. now I have a set of merlin aluminum heads on it and the exhaust ports are raised and the spark plugs are angled slightly different. they fit "ok" but a little hard to pull the plugs. also when I had the stock heads there was a good amount of room to run the plug wires under the headers. now it's kinda tight. overall I am happy with them though.
Hey Eric, have you tried asking on teamcamaro.com? They may have some insight as well.
I saw a lot of people running HOOKER headers on their big blocks this past weekend. I hear LEMON's makes a good, but expensive header.
GOOD LUCK!
Thanks for all the input guys. I have been doing some reading and it seems to be the Hookers fit well out of the box with stock type heads and also clear clutch linkage. I have not tried them yet.
I used the super comps when I had a small block. The only problem I had was them scraping on the ground, they ended up being the lowest point on the car.
