CLASS RACER FORUM - View Single Post - torque-to-yield bolts query

Ken Haase · 10-30-2008, 01:34 AM

I just picked up a used Chev 454HO crate motor. Does anybody know if those come with torque-to-yield head bolts?

Also, any idea how much increase in lift can the stock hydraulic roller lifter set-up tolerate? I'd like to get to the .580-.600 range if possible. Or am I going to need the retro-fit lifters? Thanks for any help.
