im sure a bigger cam would work better with that big of a runner..... but im in CA and the 222/224 is the biggest i want to run.
i just want to make sure that those runners are not going to KILL my power!
im guessing i may loose a little low end but not much.
and if evertone thought that using these heads was a BAD idea i was thinking i could allways build up the floor a little with some epoxy or resin or somthing?????
any other ideas would be great!!!

i just want to be confident that these heads will make good power....thanks

 

I say go for it. I think you will be fine

 

The stock ls6 runner is 210cc.

 

To give you some perspective my intake runner is 230cc.

 

I think Brian is right on the mark...one never really knows what the runner is unless one measures.

 

except the head porter of course

 

so i guess ill be fine huh? 233cc intake 83cc exhaust 69cc CC but milled to a 10.8:1 CR

 

Unless its JPR in which case he also does not know

 

anyone else?
