( New mods need input) My 500rwhp NA build 700+ on the bottle OK fellas, I finished my recent 383 strikers fully forged mods are in signature. Well my next quest is to reach 500rwhp on this 383 what do you guys recommend me changing or getting to reach my goal cam is custom from tick 239/248 I think I should be able to reach it with my current cam my fast 92/92 is not ported I know I can probably pick up 10wrhp with a mamo port: any other advise let's see Where I go next.

Sound advice above! I'd look long and hard at the TFS 220's. Setup correctly they perform excellent! What is correctly? Buy them from Tooley; get them w/ turned down LS3 intake valves (2.04); powder metal guides (which allows you to run stock GM rockers); milled to the same spec you have currently; and get Tooley to hand finish them. Best bang for the buck on the market IMO.

They only reason I keep these headers I'm running the true duals and fitment is perfect. I also have a starter bridge so I'm not sure if the new headers would be and issue for it. Also you think I should move up to a bigger head like the 230s? And if I go to the 1 7/8 I would need to redo the whole exhaust setup?

I'd second the TFS 220s by Tooley, some TSP 1-7/8" Headers and true duals... You're going to pick up probably 20rwhp just from the headers and another 15-20 from the heads. Btw, Tooley does porting on the FAST as well... so that would be worth some more.

PRC 227's or 237's 
Good choice.
TSP 1 7/8 headers
True duals(you can get the ebay SS true dual) run them to the back through magnaflows, dynomax, summit glass packs(a straight thru muff)
The cam shold be ok, I don't like the lobes but they should work.
Change all of the other stuff first. Do not port your intake untill you made all of the other changes first. Porting the intake should be the last thing you do.
