LS6 heads, how much to expect? i wanted to know whether i should purchase a stock set of LS6 heads and bolt them right up with no porting done since they aren't that expensive to buy from someone on this site, or to spend more $ for some CNC ported heads? i
My current mods are: SLP LT headers,ORY, ASA cam, 40#injectors, lid, catback.
Would the gains be significant from the stock LS6 heads vs CNC ported heads?
Any advice is helpful. thanks

I just finished a few weeks ago putting a set of STOCK 243 LS6 Heads on my car and I gained 19rwhp and 31rwtq so it was definatly worth it to me. I purchased a used set for a pretty good deal.

Well I have all the bolt ons and blew my car up and purchased a crate LS1 Motor that had the LS6 Block. Then I put the 02 LS6 cam in it and it made 382rwhp and 371rwtq. And Like I said recently I put the Stock LS6 Heads on the car and made 400RWHP and 400RWTQ on the same dyno which is a Super Flow. I LOVE my set up now also that is through a 12 Bolt w/4.10. Hoping for 11.50 pass
