There exhaust manifolds are good Now (except for having no room for the one manifold bolt to fit), you should have seen their original SS type. When it started cracking everywhere my car sounded like a 3cyl VW diesel.

Well just got a call at work from HRC while I was writing this, Bill Hahn understood the mistake and isnt charging me a restocking fee. One headache gone Has anybody else upgraded their pistons??? Did you use stock bore?
