Speedmaster heads are on and running.....

Lookin forward to the track results!!

I like that you didn’t change anything else on the combo.

I think the 13.3’s out of it with the stock heads, tiny cam, and 2.94’s was fantastic.
Anything beyond that is just a bonus........ and if it actually dips into the 12’s...... that’ll really be something.

I gained a solid 4 mph in between my markings on the back road (less than a 1/4 mile, maybe 900 ft ?) My speedometer is pretty still in that car too, so it's easy to see the gains. Tried it twice. It seems it wants more fuel since the head swap. I stomped it hard out of the hole today and got a lean snap (never ever did that before), but it launched hard with a dead hook and was gone!
