I appreciate the quick feedback guys, and I do understand that each engine will have its own setup. I also understand that I won't quite need 38* with the vortec heads.

I kinda figured this would come to a try and error thing. I guess my goal was to clarify that I wasn't thinking/doing something that those with more experience would consider incorrect.

So let me pose this one... no matter what I go with for the best idle quality (manifold or ported), if I'm in @ 32* by say 2500-3000 rpms, what happens when I'm only cruising in OD @ 1800 rpm? Am I missing out on mechanical advance and is this hurting mileage? The other piece I'm missing is this 50-52* total idea. I'm not trying to rehash this to death, but just wanted to ask a couple things I hadn't been able to clear up thru searching. Thanks.
