Head cracked on my 52 A --Have a good replacement --What do I do to get best performance? I put.090 M&W Pistons in several years ago It playes with 3--14s but while the head is off would you share any tricks you have? Leave the eyebrows? shave the head surface? how much? gonna smooth up the ports and flat surface manifold and head -- Might pull it next year
 

Put a Stroker Crank in it.. at least an extra Full Inch,Preferably More. + a Performance Cam and ALL the Compression you can afford to feed..

If you plow with it I certainly wouldnt stroke it. With the creeper gear you wont choke out pulling a sled either. If you want a little more, mill the head .150, feather back the eyebrows, match port manifold to head, clean and smooth up valve bowls, cut the rockers. That will help and will be a cheap project.
