To save the tranny. I`m going to have a stage 2 rebuild on her. I don`t spray threw shifts, etc. Will end up with a directport in acouple of years then 300 shot. Change tranny out also! Thats later plans!

if u guys get the heads in less than a month after ordering, i will probably buy a set from you

The induction system makes any combination. The heads flow 345 on a 4.000" bore. They should go about 350 on a 4.030" bore @ 28". The cam is in the mid 240's @ .050. It will run very very good. 10's N/A won't be a problem for David, even in his super heavy car.

I will have to ask the rest.

Prolly just standard LSX pistons. You'd have to run a .700+ lift camshaft to ever get close to needing the valve reliefs. Shouldn't be any kind of problem, I was just wondering.
