I was looking at the summit magazine and they have a new set of trick flow heads made for nitrous. My question is are these heads any good or should i just send my heads off and port and polish them. Im going to spray my car but im going to build a motor before i spray it because mine is about to go.

 

they say "for nitrous or boosted applications" dont they?
they have bigger chambers,so your compression will drop over stockers.

IMO if you have a stock bottom end,send the stockers off.

 

They say for nitrous applications. Im not going to have a stock bottom end for long thats why im looking into a good set of heads for the nitrous applications. What is a good combo for nitrous applications.

 

You want a cylinder head that flows as much on the exhaust as possible. Since you are force feeding your engine air and fuel, your only real concern is trying to expell all of it. Something like 260/210 @.050 would be nice to shoot for. 1:1 intake to exhaust ratios are not unheard of in forced induction applications.

 

The lower compression ratio will kill a little power,you might want to just port the stockers unless you are going with a true flat top piston that will yeild a stock ratio.The combustion chambers are larger on the trick flows to accomidate aftermarket pistons without skyrocketing compression.
