The best stroker 408-416-426-435 combination in stock 68 340 block

Well...right now I dont...since it was the head that got the **** beat out of it with the broken exhaust valve...but the old engine 360 ran 10.30s in Bakerfield....so I would say they ran pretty good.
And I wonder whose CnC program was used on them...dont know since I bought them second hand...but they were not used. I guy I bought they from was changing from eddy heads to indy heads.
