Mad Dart I'm curious as to why your switching to magnum style valve train? LA head rocker shaft system is superior IMO. Do you plan on running a girdle on the rockers? That's going to be quite alot of stress on a 5/16" rocker stud.
I bought some parts a while ago, the 1.6 Roller Rockers, JOMAR GIRDLES studs etc, and decided to use them on this build. Plus I wanted a CLOSED combustion chamber and attempt a tight quench and run higher compression and bigger camshaft on PUMP fuel if it is possible. I understand that there will be more stress and hopefully the use of BEE-HIVE valve springs will help with this issue.
I really got caught up on the EQ heads and how much flow was available for an Iron Head without the CRACKING issue compared to stock casting Iron Heads.
