Need advice on what parts to get for my new forged 355ci lt1

Well im going to start collecting my parts now for the 355 im doing this winter. I want a motor to withstand 150-200 shot of nitrous. Im doing the 355 with forged pistons eagle rods.

Basically how would you set it up. Please include a parts list.ie you dont need part numbers just tell me how you would do it.

I want to try in learn from other peoples mistakes on these. I want a strong forged bottom end for n20.

Also should I mill the heads? If so how much and what headgasket to use.

Thanks!

Joe

LOL

Well im thinking this so far.

Bottom End:

I'd go with TRW forged pistons
Eagle forged H-beams
stock crank

Heads:
Machine shop 3 angle valve job.
Porting and polishing by me(got some stuff on how to do a good buget port equal to a stage II.
1.6 rockers.
Valve size?

Block:
Using my stock lt1 block
Bored .030 over
Balanced
Splayed 4 bolts?
Anything else?

I know im missing tons of stuff. Just let me know. I want to get a master parts list going.

Also if you had part #'s that would help.



I just want to start collecting this stuff off of ebay asap.
