I have a set of 317 heads I ported a while back and had flow benched by Jim Evans in Rolla mo, these heads flow 290 CFM at .600 lift with incresaed flow in all lift ranges..

perfect heads for turbo or superchager setups looking to lower compression and increase overall power with flow and more boost ability

I also have a few other sets i'm working on, 243's 241's...but not yet finished

hi bud, do 317 fit 346 cui bore ok?
Just not sure if you require 4.00" + bore for 317.

Also do the heads come complete assembled ready to bolt on?

cheers

I have someone else interested in them right now...waiting on reply

They do fit 5.7L 346cu.in. no problem...they will come with valves and OEM springs

These heads on a stock 5.7 DROP compression!! They flow alot better then stock ls1 heads and stare the same ls6 intake and exhaust port.

People who buy these heads normally plan on turbo or supercharging their motor...these heads have bigger combustion chambers vs ls1 chamber which are smaller.

I have a TT set up with ported 241 and wanted an upgrade on a budget whilst adding some extra psi......
