Some M1 porting pictures and flow numbers

I had eddy heads/M1 ported polished gasket matched. Added roller rockers per eddy instructions and I dont believe it made a difference in anything other than aesthetics. Alot of money spent to make the runners look smooth. MP 380hp crate motor

IN my humble opinion the two problems that come to light are:

Smoothed runners don’t make power.
The MP 360/380 engine has a street cam in it. 230@050 is small.
Were the heads stock? If so, that’s problem #3.
