ProComp/Speedmaster aluminum heads

But that's cheap Chinese junk and it's going to go slow and break and blow up in your motor...lol..
Right now I'm torn between buying one of those Spring Height checkers for a one-time use or making my own redneck adjustable sleeve and measuring it when it's done? What's your thoughts...
I'm going to get the springs that are on the heads checked, but from what prh said I'm not hopeful that I'll be using them...


Buy the mic, if you don't think you'll use it again sell it. Use the right tool for the job.
