383 stroker RPMS?
 
I am building a 383 stroker motor. And was wondering what rpms I will be able to run. It has 202 camel hump heads, eagle performance crankshaft, H beam eagle rods, Molly pistons. I set the end gap to .018 top ring and bottum ring .021, Comp hydraulic roller cam with roller rockers .542 intake .560 exhaust. And a 750 SS quick fuel carburator? And does anyone know what my HP rating should be?

Engine will be done making power at 6000 RPM with those heads
450 HP maybe

heads
 
You think I could use some better heads? How much HP gain would that give me?

With a set of "good heads" a 50-70- gain is not unheard of.

If cast iron is your route of choice, I highly recommend the Dart iron eagle platinum series head.

Yes, Dart or RHS would be the to best choices.
If aluminum AFR 195
Both heads with your cam profile depending on intake will make 500 HP

What pistons and what ring size ?

I would not use the old 461 style heads,double hump,if you can budget for some better heads.I used the old iron eagle 215 heads with a team g manifold on my 355 in my 68 camaro with great success.I now use a set of the iron eagle platinums on my 383 and they are worth about a tenth over my old iron eagles.
I am willing to sell the iron eagles and manifold if you are interested.

i had your exact combo on my 383 and saw a 25-30 horse gain just going to vortecs
unless uve got some very stout springs ur power band wont go past 5500

Pistion size
 
4.030 bore. Ring gap: top ring .018 bottum ring .021, Ive already spent some bucks getting these double hump 202 machined, ported new valves and seats, and screw in studs. So I am going to run them for a while.
