Speedmaster heads revisited.

Be curious what John thinks about that.
my thought is…why?
For a ”class” type car you wouldn’t want to do it because rules wouldn’t allow it.
For any other type car, why would you throw the money/ porting, etc, etc at a limited iron head when you could buy an offset or non offset aluminum head that weighs way less, has more potential, and is cheaper to port and likely has cnc options as well.

Just curious because I have a set of "ported" J heads on the shelf that I was thinking of using for a future budget build. I use quotes because I have no idea who did the work, or to what extent they've been worked. Obviously if they'll require more work, I'll scrap the idea. I'm just curious if opening up the PR pinch to the extent discussed here is generally worth the effort on iron heads.
