Re: Header Reccomendation
I am planning on reusing my 30 year old Hooker Competition headers on the new build. It's a .060" over 454, 10.5:1, ported/polished steel 702 heads, 850 Holley, 0.540"/0.560" lift and 242/248 duration at .050".
The headers have 2" tubes with 3.5" collectors. Is this still a good header to use? I am going tomorrow to see if they can be ceramic coated. They are in good shape except for a fair amount of surface rust.
If these can't be coated, can someone recommend a full length, ceramic coated header that fits good. The car will have a stock ride height, PS, T400 and a Vintage Air compressor.
Thx in advance.
I have the same headers on my ss396 Chevelle, from 2005, ceramic coated. Sound and power are perfect. Very nasty and cool sounding. With 3 inch exhaust and flowmasters, the big cam sound at idle and WOT sound cannot be beat. There is some clearance issue that might require a dimple with the steering shaft. Big oil filter -- no problem....
The biggest issue is the ground clearance. They are not made for lowered cars. My Chevelle is lowered about 1.5 inches and speed bumps are a big issue. The lowest pipe on the drivers side has a flat spot from hitting, you can see it in the pic. I plan to change them out soon. I cannot stand how low they hang. I hope I do not mess up the sound, because they sound unbelievably great with my cam. Check pics.
PS. In this forum, a lot of people are happy with the thicker flange Hedman 2". They tuck up nice and tight. I am planning to try those next.
