I do have a set of the old style heads, they were all good when taken off for my built motor swap...

So the plugs being like that is from the blowby of oil that a catch-can will prevent? If he got one will they have less carbon buildup? Mine looked like that but my car runs just fine.

Diabolical!

Plugs are gonna build up crud no matter what, but oil in the combustion chamber will make it much worse. The 3V is notorious for blowby, even when bone stock.

OP, I wish I could help you more. There are just too many variables for me to attempt an internet diagnosis. Good luck with it man.
