Some M1 porting pictures and flow numbers

Thanks Fishmen. It’ll be tried with varying displacements over time. It has enough cfm flow to make for a good street ride. I don’t see a problem turning in a good ET at the track on any reasonable displacement for the head. At 185 listed cc, it should make for a fun mill. Not a killer mill.

I have had these a while, before the TF’s came out. They were a good bit cheaper then.

Yes! The B engine heads are nice as well.
