361 Woes

After the oil change, no change in condition. Gets worse as it sits and idles. Go figure.

Just dont think its the rings, shouldnt fall apart or get stuck overnight like that.

I am no thinking about trying to source out a set of used heads that I can give a shot at. Being that this is a 9:0:1 compression 2 bbl B motor, can I use any 383 or 400 heads, or can I use 440 heads as well?

I already have a low deck 4 bbl intake.
