7.350 was perfect with mine. Though my heads were milled to make 66cc chambers and I used a .040 gasket. Cam is a 236/242 Comp grind, so its going to be a standard base circle, probably same as yours will be. If you are using stock L92 unmilled heads, I would think the 7.375 would be what you need. However, it is best to measure as you know.

With my 66cc heads, 7.350 pushrod gave me between 1/2 and 3/4 of a turn preload to get to 22ft/lbs. It ends up being like .080 preload that we measured I believe.
