Very interested in pricing and flow numbers.
Do you guys know if the L86 heads go right on an L83? I wondered if the valves were too big and if there were any other differences. Those flow a lot more than L83 heads from what I've seen so far and was wondering what will be the popular way for us L83 guys to go, whether it be ported L83's, or ported L86's for double (double as in more flow in stock form then even more from those being ported) the gain in flow or..

I don't know but that be awesome especially with a pd blower where low end is in abundance. Now I want to know too.

Bowl blending and valve job is a large part of the power increase with ported heads and not too big of an expense. So I've been thinking maybe L86 heads with a smaller valve bowl blend and valve job could be one bad *** setup for low $$$.
I've also been thinking a LT4 take off blower would be flipping sweet on one of these trucks.

I'm sure the larger valve plays a major role in those flow numbers. If I had to guess going to a smaller valve in the L86 head would net you flow that is similar to a ported L83 head. it could also be an issue of valve placement that would make them less than ideal on the 5.3 bore.
