Tell you out front that I am not a fan of you using smog heads and yet I do understand why you are.The smart money spends on the end build with the aftermarket heads and the reason why is your likely going to spend about $200 on the smog heads to make them in decent form.Then which cam you going to use on the smog heads may or may not require additional machine work.So you lose the 200 bucks because no one wants then normally and the cost of the cam and kit for it.You get to buy the cam and kit a second time for the later aftermarket heads too.You might be better off holding off to buy the aftermarket when your more flush with cash.

Just my two cents worth.
