To trade or not to trade?

you have to decide what you want. if you buy his you will have to change a few thing to run pump gas. i don't know how much your heads would drop the compression ratio. that quite a bit of difference and would drop it but how much i couldn't say. there must be a formula somewhere or maybe pkrwud will look in and he should know or know where to find the answer.

I say build the combo the way you want.
