hey! ihave a question what kind of heads do u all think be the best to put them toguether with a 383 and a holley stealthram intake, also 30 lbs injectors and a 255lph electric fuel pump?

 

The Stealth Ram is going to be happier with midrange power production. I would choose a cylinder head to match. Try something in the 195cc to 210cc intake runner range. Choose the cylinder head with the best flow numbers in the valve lift range your cam will produce.

If all your parts work in harmony and compliment each other you'll be flying down the drag strip.

 

AFR 180cc or 195cc.I think 195cc.What size cam are you running?Those are some of the best heads but if it was a street motor 195cc with a good sized cam in the 225-235 duration would be my choice.

 

anybodyelse?????

 

i like my world products Sportsman II's. thy're 200 CC heads. there's also the Motown heads, which are 220 CC, but that may be a bit big. I think the AFR's are a bit small, but I know they're real great castings. you can also go with some dart heads, or even brodix. all great companies, but you're going to have to look at where each set makes power and find the one that best fits your desired powerband and current pars selection. if you haven't picked a cam yet, i would wait until the very last. a cam should be the last thing you select, and abse that choice on everything else you have.

 

Any head in the cc 180-195cc range that was mentioned should be fine. The trick flows seem the best bang for the buck head. All the aftermarket manufacture heads are pretty much the same when it comes to 23 degree heads since they all have the same design limitations.

 

depends on the buck. Trick flows are pricier than the world heads, either sportmans or motowns, but they supposedly produce more HP out of the box. It's all subjective. it depends on what you want to spend... if money isn't the issue, then pick what goes best with your combo. But I still think he needs something bigger than 195 for a 383. definitely bigger than 180.

 

Well most 180 cc heads actually cc larger than 180cc's. It definately depends what hes doing with the engine that will help decide. When you compare a 180 to say a 200 cc head at lifts between .400 .550 the flow is really comparative anything above that the 200 cc heads flow better but would only be useful with a higher lift cam. The main limitation of all heads is the pushrod pinch. As the ports in the heads get larger the pushrod pinch is usually the main hurdle. Larger CC heads usually have more of an offset on the pushrod pinch. Moving the pushrod offset on any head is a pretty simple task.

 

It seemed like you didn't get an answer but you really did. You will get countless opinions for which cylinder head is the best. But the common thread among all answers is stay below 210 cc intake runner for a street car. You CAN'T go wrong with a smaller intake runner. You CAN go wrong with too much intake runner by creating an unresponsive engine that only makes power when wound out to red line. So treat it like a camshaft... when in doubt be conservative.

The point is almost anything performance oriented is going to work well. Don't spend too much. It just won't matter much.

If you are on a budget, you dont want to go cheap on the heads. Spend the money on a good set of heads because that is what is going to make your power. For a budget head i would recomend the GM fastburn heads. I think these will make more power than most aftermarket heads with the same price range. They may not flow as well as the AFR's but they sure do make the hp. Good luck!

 

Those are the ones I'm lookin at for my 383. The only thing about them (and this has been brought up before) is that they require special headers/flanges.
