Some M1 porting pictures and flow numbers

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.
Had the original small heads 1.92s etc. Upgraded to 2.02/1.60 cam was 501 /513 as original
