my plan is to get a stroker 383 and im going to buy vengeance ported fast90 and NW 90 TB. but i want to have low end power and have as good as gas milage as i can get since its a DD.

i was going to get afr 205cc but now i saw trickflow 215's whats the difference in power, gas milage, and will it hold up to nitrous well?

 

Both heads will do all of those well. It's all a matter of how big of a cam you want to go with.

Trick Flows have better mid-lift flow, which is where power is made. I am currently installing trickflows on my Camaro.

 

the cam thats in my motor right now is 240/244 112lsa

 

so now one of the Q's are answered the trickflows will make more mid and probly top power. now what will have the better gas milage and what will hold better for nitrous? its already on there and i dont want to take it off.

 

Both heads will do quite well. Fuel economy is going to depend more on your tune than the cylinder heads. Both are extremely efficient. Both are also going to work well with nitrous as they both are after market castings with thick deck surfaces.

I would think the TrickFlows will make slightly more power over the AFRs, but at an additional cost of roller rockers on the TFS heads.

Either way, you cant go wrong. If I can help you out please dont hesitate to call. We are a dealer for both cylinder heads.
