What is the formula for figuring out the valve lash with the roller rockers? I see here at the sight people have many different setting from 10 intake and 12 exhaust all the way up to 20. How do you figure out the definitive setting?
In my case I have a 1.9 bored to 2.4 with the 30 over Chevy pistons and Chevy valves of 1.84 and 1.50. The head has been ported by Rodgers and should be done as close to correct as these things are. The cam I have is 430 lift 270 dur @50 with 108 sep.
Right now for the engine break in the valves are at 10 and 12 set cold in the machine shop and the engine has run about 20 min…
So now when retorque the head and do the valves where do I set it?
Thank you,
Calvin
