Specifications:
Did the exhaust seats get drilled out and replaced with hardened seats? I see this as a must, because of the modern unleaded gasoline. I dont plan on buying lead additive to every fuel tank and want to make sure these are "unleaded proof"
Are these heads compatible with 289 engines? Are they compatible with roller cam retrofit lifters? What is the maximum lift?
Hi, What is the size of the mounting bolt 1/2 or 7/16?
What are the size of the valves? Any issue using roller rockers?
Can I use these on a 1976 Ford 302? And use ARP head bolts that use the spacers for the 7/16 bolts.
