ProComp/Speedmaster aluminum heads

i have a set of the cnc speedmaster heads on a 360 . I bought the heads bare and had the local machine shop i use do a performance valve job along with new valves and pac springs. They also put them on their flow bench and they did not set the world on fire.... The engine had another problem that did not allow us to get some good time slips in before the summer shut down in Vegas. Track reopens in September....

The engine has been repaired and camshaft changed out...I got a long list of things to do to the car but not sure if everything is going to get done as I want to run it at the TnT that Friday night. Trying to get roll bar in car with hope it runs fast enough to need it...LOL>...then the lightening of the car is needed for that 75 Duster....going to get rid of the heavy bumpers ...brackets...and shocks...putting a earlier front end on the car along with fiberglass hood and bumper....
