I have a 1980 Chevrolet truck with 25,000 miles runs rough at idle tuned up and rebuilt carb still runs rough. Is it the Integral head? What year head would be good to change it with also what exhaust and intake manifolds would be good to use also carb. and where would be a good place to get parts also what about the power steering pump do I need a different brackets and pump.Has anyone done this? Please let me know!
Thanks

basically, any year besides the intergral head is better than before. you can usually find intake and exhaust from someone on here, check the classifieds, or if you want hipo stuff, ebay has some good finds for offy, clifford, etc etc.

as for PS..no idea. my '69 doesn't have it. lol. just one big ass steering wheel.

if you want simplicity, you can;'t beat an offy 4 bbl intake, with like a holley 500, or Carter/AFB 500..anything in the 500 cfm should feed 'er quite well. the offy has skinnier runners for more streetable low end torque, which is what these 6's aare made for.


greetings from Northern Wis, and cheers to keeping it InLine.

First before you start thinking about changing the head have you checked the smog laws to see if you can???
Have you tried adjusting the valves? I'm assuming they are adjustable. You might check the compression before and after adjusting. 8-)
If you change the head yes will have to modify or replace the power steering bracket, not the pump in most cases.
