will this cam work with stock lifters and push rods

Asked by: sixpak
You will want to use the kit that includes lifters, you cannot reuse flat tappet lifters. Your stock pushrods should work, but you will need to check the length after installation.

Will stock heads work with this cam for the valve clearance

Asked by: Johnwayne
This will depend on the pistons and cylinder heads that are being used. This will work with most applications.
