Center punch the piston down the guide at 10 degrees before or after. Use a compass to sweep the reliefs you have to see where you are at. Set compass at half valve size. If you have B-1 pistons in it you may not have to do much to the reliefs if the piston manufacturer was a little generious with his cutter. Frank Its the exhaust that moves... thanks for that info... I thought it was the intake... I sold my B1M/C heads so I dont have them anymore to look at I was told By Scott Koffel to be able to reuse the MC rockers with Original heads, the exh rocker needs to be moved .040 towards the intake valve. So I assume the intake is moved away from the intake towards the wall? to allow the larger intake valve? Last edited by Bob_Coomer; 09/23/11 05:26 PM.
