I picked up a 7120 head yesterday form the JY for $40 and took it into my machinist to have him work on it. Can't find any 0630 heads anywhere for cheap.
My machinist suggested I take off .040" off the head and run a cam with matching springs. Bumping the compression.
Comp camps extreme 4x4 cam, 68-232-4, look like the winning cam. They suggest using their own valve springs, CCA926-12 but these have a heavy spring rate and the spring retainers wont work either.
The only winning valve springs are the Mopar P4529214 but those bastards are $15 a piece!!!
My question is: Will I have valve issues if I mill off .040" and throw in the cam plus valve springs on a stock bottom end block? My machinist is going to work on the valve stem seals and such to match it up.
