ok guys made my purchase have a cam, clutch, full exhaust, ls6 oil pump already installed. parts list is this
PRC 220cc 5.3L Stage 2.5 CNC Ported heads
hardend push rods
fast 102 mm intake and throttle body
fast fuel rail kit
fast 36 lb injectors
spark plug wires
head gaskets and all other gaskets

I think that is all any sugestions on what spark plugs to run

 

you might want to add new lifters since heads will be off the car

 

lifters, timing chain, I'm assuming the heads have upgraded springs, plug wires, maybe a new slave cylinder, etc....

 

Rearend to hold the power

 

Since it is apart upgrade to ARP studs

 

oil/coolant
pickup tube o ring
water pump gaskets
balancer bolt
you will need an aftermarket intake of some kind. i dont think the 102 accepts stock size bellows.
header gaskets

and like he said, a rearend

 

agreed
