yeah i know....i guess what im trying to ask is at low rpm is there anyway your can fill the cylinders with too much air....(like when ur running extremly rich it tends to bog instead of picking up quicly and smooth) can you get this same effect with air? lol i know what im trying to say but dont know how to explain it....or is bigger just better in every way? if so then i dont understand why manufacturs would still make 1.9 in intake valves when there is a way to get 2.02'son itwith stock pistons.

If i were you id look at holley heads i am, i got a kb on my 94 and the holley heads are only 1.90 head andthey flow aboutthe same on the intake side as most other heads excluding afr and trickflow but remember that you dont need a big intake because the supercharger will be forcing it in and a supercharger just adds to the fact how bad 5.0's are on exhaust flow. The holley head flows the best on exhaust better than trickflow better than afr, although i still think they want too much for em, there the best supercharger head in my opinion, also because i recently discovered other 5.0 kb users and when i brought it up they both said holley all the way for stock pistons. Plus its a 63cc head which would allow u to run more boost than with the smaller 61cc tw chambers unles you did some machine work.
