with the 305, the choices of heads are not that big. So the world torquers and the vette heads seem to be the only ones.
The claims are ~60hp improvement for heads and cam. But i'm wondering what torque gains i can expect for this upgrade, since the car is only street driven? (damn, we don't have any race tracks here... )
Anyone can help me? (dynosheet are welcome )

Thanks
Pat

TrickFlow now sells a head with 58cc chambers, 1.94/1.50 valves and 175cc intake runners for the 305. The post 1987 ones are about $1,000 from Summit.

you can use from 416 casting heads.. those are the HO heads and flow pretty well when ported

Damn are they really this expensive???

I'm wondering if they are a direct bolt-on or I would have to do some stuff like EGR rerouting...

doesnt dart make a 49 cc chamber? seems way to small
but another option

swisscheese

nahh, its 44cc!
probably would fit the V40 T4 since they are writting "works well with turbo"
