I'd suggest that if you are going to go in to the effort of taking out the stock stuff to prep and clean and so forth, then just do the forged goodies.
also, I don't see how you are planning on using stock pistons to get a 8.5-9.0 comp ratio.
You will get about 8.3:1 unless you shave a bit off the block and possibly head, then you get in to all that quench zone bullshit which I don't understand.
The guy on here (can't remember his name) sells the pistons and rods as a pack for a 9.0:1 comp ratio and they slot right in.
The only time I think the standard stuff should be considered is like a few people here have done.
STOCK bottom end, UN TOUCHED, bolted to head, UNTOUCHED.
Essentially, a BUDGET RB30.
if it pops, you put another $100 jobbie in there.
considering you have a fancy head on yours, I wouldn't risk the chance of a meeting between the CEO of the pistons, team leader of the rods and Managing Director of the valves.
