Question for you guys, I have a 1982 Camaro and going to build a 500hp 383 engine. I would like to go with aluminum heads for weigt, cooling and power but if the engine overheats once your screwed do to warping. So i was thinking cast iron which cast iron head should i use to make good power and flow for a 500hp 383. Any help would be greatly appreciated.

Thanks,

cast iron warps too if you over heat the engine. i don't think i'd limit my options on something yuo shouldn't allow to happen any way. also a warped head is repairable.

 

I agree, as long as you've managed your cooling system,
you shouldn't have that hanging over your head.
As far as head choices I went aluminum over cast iron.
Needed that lightweight for intentional racing purposes,but cast iron heads also have advantages over aluminum so...
It's basically a matter of YOUR choice.DUECE

 

My car has only overheated once due to a thrown belt, since then I switched to a March Pulley system, cast iron headers and had a custom aluminum radiator with large fans installed and has never overheated since came close once driving in the woodward dream cruise. Which heads should I use on a 383 500hp engine, that will be used for the stip and used as my toy on the weekend.

out of curiosity who makes headers out of cast iron and why would you make headers out of cast iron?

 

i think he ment cast iron heads

 

oo that makes more sense.

 

Sanderson makes the cast iron headers they dont burn off a ton of heat like tube style headers www.sandersonheaders.coms. I was referring to heads though. I was thinking AFR 195's or Pro Topline Lighting 23 degree. Gonna be used on a 383 500hp engine. Looking for ideas.

Thanks,
