Thank you for the information.
Thank you espically for the above graph. That has a TON of good info I was looking for, (such as the spring pressure at height info).
But I think coil bind will be a problem.
1.560 was our shortest height.
Coil bind is at 1.100
That puts us at .460
Our valve lift on the exhaust is .466.
That's no bueno.
I'm pretty happy with where the intake height came out. One .015 shim on one spring and they are all within spitting distance in my opinion.
Thank you again for all the info. That chart is great. Thanks. Eric
