408 stroker head gasket recommendation

Calc I ran (with 1008 fel pros) gives closer to 10.3…the thinner Mr.Gasket will get closer to 10.6. May just need a little less timing to alleviate concerns, but depending on where you’re planning to make 500+ your intake closing may already be sufficient to keep cylinder pressures (and pre-detonation) at bay. Hit up a dynamic compression calculator…if your cam is in the 250’s or higher you’re probably 8.5 or lower and in premium gas range (unless your setup is heavy or under geared).

I ran oil through push rods with the regular cam timed oiling without negative effects. What’s your reasoning for wanting to cut off the oiling? True roller rockers, or..?

Another cheap/easy block if you’re still wanting it is to drill another hole in #2&4 cam bearings (between the ones that are there) and use that hole for oiling the cam. The rotated bearings will then block the oil to the top.
