I have a spare engine that I am currently building. The block is all set with je pistson...etc, crower rods, arp....etc. Now I want to build my top end. I plan on buying #0014 crane turbo cams, stainless steel valves, crane valve springs, and Eaton PT Cruiser Style Lifter/Lash Adjusters. I was going to order all this from howell. Should I send my head to anyone to have anything done? Should I buy this stuff? Thanks
