Oops I was doing some correspondence with Zippy to get another head and picked this very old thread by error!
The M2 head is a much better casting and has a revised exhaust port.
Most of the newer design hemi heads are “all about the exhaust issues”.
Obviously when the original head and ports were ‘canted over’ for passenger car fitment, it reduced flow...
Now the M2 head is ‘way out’ of production, it’s a worry indeed!
Lots of folks need one or two M2’s for their current builds...
Edelbrocks themselves are in a big moving scenario and deny even casting the M2’s...
But a very nice man did email me to say, they will be available soon?
How did he know this if they don’t actually make them lol?
