TSP LS6 heads with stock size vavles I am looking at the LS6 heads that TSP sales with stock size vavels what would you guys say about it matching up with the cam I have now
238/242 .605/.610 110LSA+2
I am making 412rwhp and would like to be more around 440rwhp or more
Also I did not have to fly cut the pistons and would like to stay away from that and that is why I am interested in the LS6 units with stock size vavles
I have the crappy 853 (or what ever) heads and I think the 243 casting would be a big improvment specialy being ported, even with the 2.00/ 1.55 vavles
I have all supporting mods (all bolt ons) and I have ARP rod bolts so not to worried about breaking the bottom end with putting out to much power for the stock short block with 63000 miles.
These heads are just such a great price that it makes it realistic for me to be able to afford them.
Thanks for the help

Mine made 432rwhp untuned. That was from 410rwhp cam only...through the exhaust and ls6 intake. Im getting the tune dialed in now with EFILIVE and Im thinking/hoping Ill make 450rwhp....the tune was really FUBAR before. 
Cam is 228/228 comp XER....

I am doing that with one of my motors......
stock ls6 bottom end, LS6 intake, arp rod bolts, headstuds, tsp233/239 or maybe a trex, PRC ls6 heads, and probably a 100 shot.
I am probably going to start out with the 233/239 and dyno, then switch to the trex and dyno. Keeping the best out of the two. By best that doesn't necessarily mean peak hp.

I plan on using these with my big cam when I get the money. They're great for big cams, and don't const too much at all.
