Speedmaster heads track results ?
I know there are several older threads on these affordable heads and I try to keep up on others posts related but after 2 years I still have not seen any track results or impressive performance done with any yet. Covid screwed up a lot of folks plans over the last year but come on the tracks were open. I have only seen a mild 400 something horsepower dyno thing that didn't seem to be anything a regular iron D port could do so that's why I am asking. Were halfway to maybe yet another big sale clearance in 6 months from now or so that's why. Thanks
