    No reason to do so. Actually from my own personal experience, on my own vehicle. When we did this I actually lost noticeable power. With stock heads of-course.

    youd have to gasket match the heads with it for it to make any difference. otherwise there will be a step from the lower intake to the heads.

    Still pointless. The heads aren't the same size as the outlets on your ported LIM. All it's going to do is cause turbulence in the airflow.

    I was referring more to the inlet of the LIM... make more use of the IC core.

    would that also make more use of the sc or not with the outlet size only being so big

    if I happen to find another or fix my totalled car prior to your purchasing my blower I can surely add my ported LIM in on the deal for an added price (inlet porting only)

    but that is up to you PS I sent pics, I found them on my girls photobucket

    yea i saw that. i didnt know if the inlet porting helped any, but no need to by it, i can inlet port myself (cut off wheel!!!!) haha. im thinking im gonna stay stock lim now, cause i noticed that lim gasket plus some other stuff that i would want to replace would cost me another 50 that i dont need to spend at the moment (thanks though)
