Yeah, I may be shooting a little high... 300 hp/ft lbs a more reasonable goal? So a stock rebuild kit should do just fine correct?

So for pistons I have: http://cgi.ebay.com/ebaymotors/250-CHEVY...%3A1|240%3A1318

Exhaust Manifold (wow I hope there is a cheaper version of this thing...) : http://cgi.ebay.com/ebaymotors/SPA-Turbo...sQ5fAccessories

Intake Manifold : http://store.summitracing.com/partdetail.asp?part=OFY-5416&autoview=sku

ARP Head Studs : http://store.summitracing.com/partdetail.asp?part=ARP-132-4001&autoview=sku

Is all of this correct?
What is done to get the rods reworked for strength?
Any other parts needed/ recommended?
