Does anyone have these? I have a 355 setup for spray and will be using a LT1 intake, would this be a good head? I would be porting these, he says the intake flows 171 right now.

 

At what lift does he say they flow 171cmf. World says they flow 221cmf @ .500" intake. If I were you I would not buy these, save up and get some fast burn heads. You will be much happier with them. But if you are looking for some decent heads right now go for it.

 

i got them. i got a lift of 515 with 1.6 roller tips
,i havent started it up yet. mabe tonite wil be the first nite for em

 

HOld off on the S/Rs. The Fast Burn is a real nice head. There's so many good ones out there, it's hard to choose one.

 

You can get those heads for around $600 SHIPPED from
www.competitionproducts.com

 

Pro Action Iron Lightnin' heads outflow them all out of the box. The LT1 intake is "de-tuned" so it will like the really big ports. They are just as cost effective and World Products heads.

 

Yes I second Pro Action heads. Any of Pro Action's heads have excellent velocity designs and are very good cost effective heads. Too bad no one knows about them.

 

well i just fired my motor up for the first time,these heads arent that bad. i like the way it runs.

 

...and can be ported to produce even better flow numbers. There is definitely some extra iron there. Too bad they don't offer 305-specific designs.

 

They probably dont because they're a drag race oriented company, and who builds a 305 for drag racing?
