Any bolt on advantages of running a silver diamond head on a stock C-301?

Yes, good compression increase and better air flow. Need to use SD push rods, valve cover, rocker arms, and 1/2 of the head bolts are a different length. Check valve to piston clearance as well.

Why not just use the SD 308 truck engine? I assume it will bolt in the same to the 560 bellhousing.

Got a blue diamond slant valve head is this any good. Looks like the port is smwaller

the port is small but the slant makes them flow better i would choose that head if i was going to be getting pistons made and a port job

I have the silver diamond head. Valve cover, head bolts, pushrods, rockers, etc. Head has a small hairline crack in one of the valve seat areas, but it was a runner and did not leak coolant when I removed it from the truck. Call or text Neil @ 608-317-7321 for pictures or questions. I will let it all go for $250.
