    PCE281.1159 - Speedmaster Bare Cylinder Heads is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Better than what many "internet" mechanics say Yes they are actually Procomp heads. Comes in a Procomp box. They are pretty good castings regardless. No they aren't AFR quality heads so don't try to compare them. There is a reason those are $1500 plus heads. If you want a decent cheap head there are just fine. I'm building a 383 Stroker and just wanted a better flowing head that flowed better than my newer stock vortec heads that i had. My car is a street queen and will not see the drag strips. I bought the bare heads because if you don't they will give you cheap components and that's when bad things happen. I've order all Comp Cams parts which will make for a great head.
