silverss05 Posted May 3, 2013 Report Share Posted May 3, 2013 Would either the 243 or 317 heads be a good upgrade with the mods in my signature tbss intake ls6 spring and XR265HR...212/218 .558/.563 115LSA cam. This is only if I can get a good deal on the heads. Quote Link to comment Share on other sites More sharing options...

chawkins6789 Posted May 3, 2013 Report Share Posted May 3, 2013 317's are stock heads I think. Sent from my DROID RAZR MAXX using Xparent Red Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
rdavid0412 Posted May 4, 2013 Report Share Posted May 4, 2013 Depends on if you want to stay NA or boost in the future Quote Link to comment Share on other sites More sharing options...
silverss05 Posted May 4, 2013 Author Report Share Posted May 4, 2013 I will be staying NA Quote Link to comment Share on other sites More sharing options...
chawkins6789 Posted May 4, 2013 Report Share Posted May 4, 2013 Then 243's. They will raise compression though. Sent from my DROID RAZR MAXX using Xparent Red Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
silverss05 Posted May 4, 2013 Author Report Share Posted May 4, 2013 Is it worth it if I can get the pair of heads for 500? Quote Link to comment Share on other sites More sharing options...
rdavid0412 Posted May 4, 2013 Report Share Posted May 4, 2013 Thats a little high but not too bad of a price. T Quote Link to comment Share on other sites More sharing options...
BattleAxeSSS Posted May 4, 2013 Report Share Posted May 4, 2013 correct, 317's would be your stock heads, and it would depend on what the 243's came off of, but either way, they would be an upgrade and a boost in compression which is a good thing. What are the 243's off of? Is there a specific reason why youve chosen that specific cam?? Quote Link to comment Share on other sites More sharing options...
silverss05 Posted May 4, 2013 Author Report Share Posted May 4, 2013 (edited) The heads I saw were off a 5.7 don't remember the year. I choose that came because my truck is my daily driver and didn't want to change my TBTC out just for the cam. I also have to pass CA smog.

BattleAxeSSS Posted May 4, 2013 Report Share Posted May 4, 2013 I would suggest looking to see if you can find a set of 243's off an ls6 which would give you a drop of 6cc's in the combustion chambers compared to your stock 71cc. Ok, but just so you know, even a 3200 stall is very driver friendly, which is what im running in my daily driver sss. Quote Link to comment Share on other sites More sharing options...

I have not had my TBTC for very long so I don't want to pay again for a new stall and labor until I need to repair the trans. I'm just trying to do a mild cam. I'm just curious if I can find the heads if its worth it to do the upgrade while getting a cam and tbss intake installed. Quote Link to comment Share on other sites More sharing options...

silverss05 Posted May 5, 2013 Author Report Share Posted May 5, 2013 Or there are 243 heads for sale off an ls2 on performance trucks with ls6 springs. Quote Link to comment Share on other sites More sharing options...
silverss05 Posted May 11, 2013 Author Report Share Posted May 11, 2013 (edited) If I got the 243 heads, how much do I need to have milled off to fit the 6.0? I have heard any where between .25-.30".
