Specifications:
What’s the maximum lift you can run with the provided valve springs?
Will these heads work with a flat tappet cam?
Can these be used with a 89 5.0 Block with a roller cam?
How come every company list this part number at 60 to 64cc combustion chamber size and here now 59cc, what is the true size!
Would this work on a stock 1996 f150 5.0 302 efi and would it be good pair with the trick flow stage 1 cam
