360 LA getting oil in #3 cylinder.

I took the passenger side head off to see how it looked. The gasket wasn't blown out anywhere like cylinder #3 but, there were several places where there was carbon across the fire ring. The Fel-Pro 8553 gaskets were installed.
Both heads are at a race engine machine shop to be checked and cut if neccessary.
I am planning to use the Fel-Pro 1008. I am also planning to use new ARP head bolts.
