[big gear head]

I'm going to be building a 327 for my dad's '55 Chevy. We are using a Comp Cam and some of their new coated lifters. The coating is supposed to fix the problem. It's not just Comp. Most of the cam cores and lifters come from the same place and are sold by many brands. Use oil with a lot of zinc, even after break in, and break it in with low pressure valve springs.
