i need some help deciding on what heads to go with. it will be put on a stealthram 383 roller motor. good deal? will they work?

im hoping for close to 500 flywheel HP and the cam will come next after i purchase the heads

thanks for the help guys and gals

 

Those are excellent heads. But probably a bit large for the application at hand.

You will probably not see 500 FW HP with a Stealth Ram. That unit flows about 425-450 HP.

 

RB its good to hear your voice . 215 does seem kind of large however what about the dart iron eagles 215? i might have found a decent deal on them but would they work okay???

 

Look at the runner design of the Stealth Ram. Look at one in the flesh if you can, measure the ports, study the runners. Pick heads that match with it.

For instance, I don't think you can make a Stealth Ram port out to a 1206 intake gasket (typical 215 head port size); even if you could and did, you'd really just be adding 8 little mini-plenums starting at the head flange. Counterproductive. You'd have this kind of long skinny port that ballooned out at the end into a chamber between the intake flange and the valve.

Look at heads that match to a FelPro 1205. Those will be better matched to that intake. 200s would be the size to look at in general. Another clue is the intake's flow.... it flows 240-250 CFM per port IIRC, so ideally you'd want heads in that flow in that same general range, not too much more.

 

ahhhh, so very true. i figured if you ported out the end it would help however i guess balloning it out doesnt make much sense. would you have any good suggestions as to what heads fit the 1205 gasket? i am idealy looking for a 200cc runner however if i find a good deal on a slightly larger one i dont see why i should pass it up.

i am measuring my stealthram right now....

thanks for all your help

 

I'd think any of the better heads with runners in the 200ish range would do nicely.... Dart, Brodix, Canfield, AFR, TF, maybe even some carefully ported (not "hogged") Edelbrock RPMs. Basically, any of those that come ready to port to the 1205 size. Do that plus gently massage the bowls and guides for smooth flow, not for enlargement. You'd end up with heads that will flow all that the intake will (i.e., bigger won't give you more power); plus they'll keep the charge velocity up, for good low-end torque.

 

alright, sounds like i need to keep my eyes out for a 200cc runner then.

thanks again RB.
