So I have read, and read, and I still have to ask. Now building a LQ4 with a LSA supercharger. I had worked out a set of 243 heads with some mild port work to start out N/A, was then going to turbo it, but since the packaging is tight, and I am getting lazy, going the LSA route now. Just wondering on the LSA, should I run my 243 heads with the adapters, or change over to the L92/LSA style? I have read so much about loosing low end torque with the L92 style over the older style, but I will also have to run a adapter, so I hear they work, but in the end, will I be better with the correct style heads? Cam is up in the air at this point, and I am thinking I will run a 2.5 upper pulley. Looking for 11-12#'s of boost. Thanks for any input!

After speaking with the cam guru, he says run the L92 style, and after speaking about a certain local car, that has a record, I can't disagree with him.
