I Might Have Found Something Pretty Cool.....

Question, guessing that you are doing the shims for the shaft relocation because the 318 valves are longer than the stock slant valves, does B3 need the head and short block to get the shims right, or do they work off photos or just off valve stem lengths? And roughly what does that cost?
And if I understand what B3 is doing their shims are tapered so they not only move the rocker shaft up, they also move it sideways, is that correct?
Thanks

He needs one measurement with a T square straight edge against the valve stem and the other end on top of the rocker shaft. From there he needs the measurement of the gap between the metal rule and the valve tip. Mine was .040". And yes, the shims move the shaft both up and over. The 318 valves are longer on the order of .300" which is great for me, because I needed more room for a good spring for the roller camshaft. They are going to set up right at 1.8" with about 160 on the seat. Perfect for a low lift (.488") mild ramp solid roller.
