I really appologize, Mach1, but I don't know what the compression is with the heads milled .030. My combustion chambers have also been polished, so that took more material out, thus possibly negating any rise in compression that I gained. I am running the stock pistons, so there is no P/V clearance problems even with the 1087 cam that I am using, although I did have to shim the rockers a bit. As far as what I was saying about the ports was that my buddy was simply saying they didn't line up well from the E'brocks to the TFS intake and this caused turbulence, which, in turn caused a decrease in both HP and TQ. From what he was saying, the TFS is larger than my E'brocks, causing somewhat of a 'lip' or ledge that the air has to pass before entering the combustion chamber. I then went on to say (but not explain very well) that because my heads have been milled, this would cause the roof of the ports on my heads to sit even lower then where they normally would if not milled, causing this 'lip' to be even worse.
Again, I appologize for not being more help. I really need to have my compression checked...
