1972 Dodge Colt

I have a couple of the aussie-speed large bore composite, but going to save them.
I had been running a steel shim, but that is what started leaking oil last time out.
Was it a combination of used up head bolts or something else, I am not sure.
So to keep from tearing this thing down again I am using a fel-pro composite this time.
I will loose a little compression I know but, keeping it together while I learn to drive the Colt is better.
Sides, I have been catching grief about this street engine I am running so I have a couple in the wings.
They should be "race" engines!
