318 Exhaust valve differences

yellow rose said
It depends on how wide the seat is. Most of my stuff was .040 on the intake and exhaust. The 50 degree stuff was .060 so anything under .080 on the intake and .100 on the exhaust will run fine. Might not make the best power but they will seal.

I have fine and coarse compound.

Just use the fine?

I use to have blueing dye. I'll have to look around for it or buy some more.

Thanks again for all the help guys.

It takes a message board to build an engine. Lol
