So I have this "parts/core" motor sitting here (200 crank and rods bare head and block)
I was thinking of having this head and blocked worked over for when I build a high boost 250 (pretty much just swap rotating assemblies between the two motors)
I know the BBC/Cleveland rockers will work but how does one do it? the 250 uses a 5/16" bolt and the roller rockers I have seen are 3/8" or 7/16"...is there enough meat in the pedestal to drill and tap larger? I have some small cracks between a couple seats so it might already be goign out to a welder for a little repair and didn't know if I should have the rocker arm pedestals beefed up too?
with a stud mount adjustable rocker I will need a guide plate and the pedestal cut down shorter? (I had to have the pedestals milled down on my SBF heads on my s10 because the hex on the stud would hit the rocker and keep it from sitting down all the way)
Do I just need to find a GOOD shop to do all of this or am I over thinking it?
