EQ Heads and stock rocker arms?
Also Playing around with a DCR calculator online I got a DCR of 8.36:1 using the hughes 222/226 Cam (
Hughes Engines) and an assumed static comp of 9:1. Using the originally linked 218/222 cam from the first post puts the DCR at 8.4.
This is with a conservative bet of 9:1 comp static. Thinner head gasket and theoretical 9.5:1 SCR would brings the 222/226 cam up to a 8.82 DCR.
