I can see that it is a problem in a smaller intake runner & low port.Well, do you think closing up the port so much that it never intersects that hole or moving the port down would be a little more "disrupting"? This is common in small block chevy heads and isn't a big deal.
It is present in smaller runner/lower port heads also, but it just isn't a problem. The bolt doesn't extend out of the hole into the port, but you do use a thread sealant on the rocker arm studs/shaft mount pedestal bolts when assembling the head.I can see that it is a problem in a smaller intake runner & low port.
Does the bolt extend though the hole or is it the opposite?
Sounded like good advice for the competition, He He. There was a local smart ass one time that asked me about the surface rust in his cylinders(tore down for head gaskets at the time). I told him it would help the rings seal back LOL. You should have seen the blow bye and smoke!!!Poor attempt at humor I suppose.
