please dont flame or make me look stupid, i'm just trying to find the fastest way to stop my car from burning oil.
Where should we start? The first thing I would do is go to
This is the best website I have found for identifying heads and/or any Chevy casting numbers. This way you know what you are dealing with.

  • What is the CC (Combustion Chamber) size, 64cc 76cc 80cc ect..
  • If the heads are from the early to mid sixties they might not have accessories holes (alt, aircon, power steering ect).
  • What size the intake and exhaust valves are? 194 intake 150 exhaust ect.
  • Are they High performance, passenger car, or truck heads ect.
  • Did they come on a 262, 283, 302, 305, 307, 327, 350, 400?

This is what I would worry about:
  • Do they need to be rebuilt also?
  • Will I drop my compression ratio or increase it to much?
  • Is the original engine in your Camaro stock or moded?

There are so many variables when it comes to this issue. Spit some info back at me and I give you my opinion on what you should do.
