    Rated 1 out of 5 by from Low score on quality control I bought these after reviewing Car Craft's 8 Budget Heads Comparison. I liked the peak torque produced about 4,000 RPM with the combo used. When I received them they were still full of aluminum shavings from machine work. There were spots between the intake ports that were as thin as 1/16 of an inch. The exhaust ports also had about a 1/16 of an inch of material between the port and the bolt holes to mount the headers. The guide plates did not line up with the pushrod holes in the heads. The intake ports have an obstruction in the casting. I returned them and stepped up to a pair of AFR 180cc Street Eliminator's which I will review when I receive them. I have used cheaper heads than the Jeg's heads (ProStar) and the quality was better at 2/3 the price.
