I was just tryin to Compaire prices on heads... and how much does a good set of preformance heads cost?

I found this one but does this mean its the set or would I have to buy two?

Anyone know of or have and sugguestions on a good set of heads if i wanted to get at least 400 HP with a 383 Stroker engine?

Thanks for the feed back!!

 

they are sold individually, you should be able to make well past 400 hp with those heads, but you might try patriot, they have some nice assembled heads, just call a company you like and ask them.

 

I see. They are sold in pairs.

Would somthing like THESE be of good quality? Reliable?

 

the intake runners are too small for what your wanting besides edelbrock flows about the same as GM heads. Sick

 

Sorry man... im lost on that one..
so you'd sugguest me not to get Edelbrock?

Do you want iron on aluminum? For Irons, these aren't bad.

Edelbrock is over rated.

 

the heads your are looking at have 170cc intake runners. thats too small to produce significant horsepower with a 383. look for something in the 190cc range. wouldn't go much larger than 190cc tho. the larger the intake runners the slower your take off will be due to the loss of air/fuel velocity. Edelbrock aren't much better than GM heads. for the same price you could get a decent set of Dart heads. Sick

 

GM and Edelbrock heads are ok. But for higher horsepower, you do want larger runners. If you want your power band in the lower range, I'd go with what Shnormo said. If you want them around 5500 RPM and up powerband, then you'll notice a difference with the others.

 

I would think for 400 hp .. 200 cc and under would be fine.. Budget wise look at dart iron eagle platinum, Email Dart tell them what you are planning and see what they say... If you are willing to spend more look at the new afr head they are 195cc they flow great across the whole range. Bigger heads are suited better high stall converters/high gear ratios.
Using DD dyno as a example
383, 10:1 comp, old afr 195 cc, carb 660 cfm, small tube header with muf, 510/510 hydraulic 400 hp at 5000 rpm.... 476 torque 2500 rpm !!!

 

I really want a copy of desk top dyno
