Well so far so good with the Speedmaster heads. I don't have any complaints whatsoever at this point... There certainly seems to be no lack of performance...
I drove it to a little cruising Tuesday night and it ran great..
The car drew a big crowd.. many good compliments...
Not only the engine compartment but the stance of the car..
Anyways from beginning to end and just being curious about the heads to having them on and running them I feel so far there is no losing side.. except that I should have got them in the first place LOL...
