Valve Clearances

289 · 10-20-2003, 12:37 PM

I'm going to have a setup that creates a .510 lift on my stock heads. I'm already goin to get new springs cause everyone said I should for this lift. Should I worry about clearance from piston to valve, and if I do how do you figure that out.
Thanks

Not unless your heads are milled. .510 should be fine with 1.6 RR

you say with 1.6 rr's I'm using a .480 lift steeda #19 cam in combo with 1.7 rr's. I was told the total is a .510 lift is that alright.

Yeah that sounds right. You shouldnt have to worry about piston to valve clearance.
