Head work questions

Thanks for the quick responses.
Should have mentioned I am going with Mr Gasket 028 head gaskets and factory 4 barrel intake
I will be running a Lunati 60402 cam. I already have the comp cam springs
And the exhaust retainers are the rotators so I will swap them out

That cam pushes the Crane 901's to their limit IIRC. I think the max lift for those springs is .490". They coil bind at 1.10" That cam also has some real steep ramps for their seat pressure.

The recommended spring is a Lunati 73949 dual valve spring. Dual Valve Spring W/ Damper - 1.440" O.D., .950" Coil Bind, 363 Lbs./In. Spring Rate (Qty: 1) - Lunati Power

Here is the Lunati 60402 cam card. Cam Spec Card :: Lunati Power
