Is it OK to restart this thread (please)?
As a hemi newbie I’m perplexed by MP hemi heads?
I have an older MP head and a newer MP head which is a M head.
They are slightly different outside and very different inside lol.
The exhaust port is obviously revised and larger.
I have opened up the earlier head to mimic it (as best as poss).
This is what happens when projects take decades instead of years lol...
Now I see the M2 is in circulation now!
What’s the story on these babies?
