What do you guys think of the speedmaster bare aluminum heads

pittsburghracer said

I know of 3 critical area real quick
1. The pinch needs addressed on almost every small block Mopar head

2. Short turn needs widened and shaped

3. Valve throat needs opened and sized to the valve size you are using (88-91%) and is most often ignored.

Got before and after pics of #2? I think I understand 1 & 3 but the discussions around the short turn still don't fully click.

I picked up a lightly used set of the standard ProMaxx heads from a guy that is going with the new TF and while the out of box performance of this should be much better than my J-heads, if there is some easy HP to pick up I wouldn't mind rubbing on them a little. I contacted ProMaxx and he quoted $800 to get these CNC'd and the bigger valves that he does on the Shocker 185 version. I'm only into these for $900 all up so that might not be a bad next step if/when I stroke the 340.
