Speedmaster heads for SBM

So anybody else know anything about these good, bad, or otherwise, if the runners and chambers are nice, and the castings are good, wouldent a good gasket port match on the intake and exhaust side and a smoothing out of the runners without reshaping them work. I have dont this with mopar 2.2 ,turbo heads before just matched em to the intake and exhaust ports and smoothed out the runners and valve pockets.

Aluminum heads are definitely easier to do this with compared with iron heads. I wonder how much lighter than stock these are.

I bought a set bare, then ordered the Chevy valves( they have the correct diameter stem) p/n LIBTX2021 intake, 2.02" +.100", & LIBTX1601exhaust 1.6" +.100" $8.5 per valve a

few years back. Valves are stainless steel. Nice fit. And already had a back cut on them...I wasn't looking to spend a lot of money or time on them , so I just lapped them in with valve grinding compound and install Chevy hydraulic roller cam springs....money well spent. A good bump in flow at minimum cost. I got my valves at Benning Auto and machine Columbus Ga. Phone # 706-322-8235
