Ok i just saw these on ebay!! what do you think bout these? right now ive got the LS1 heads on my 99 ta but im wanting to get them ported and polished. but im wanting a better flowing and bigger valve sized, so the motor can breathe when i get my ms4 or ms3!! he shows the part number but where can i check it out at to see if there truly ls6 heads? would these be better than a ported and polished ls1 heads? http://cgi.ebay.com/ebaymotors/PAIR-...spagenameZWDVW

man, i don't believe that what you posted up are LS6 heads... stock LS6 heads will either have yellow or blue springs, and more importantly check out these LS6 heads in this link... the quickest way to tell if they are LS6 or not is to look at the "D" shaped exhaust ports

thanks i was looking at those heads and thats what i thought i didnt think they were ls6's but i figured i would ask!! so these ls6's will surely out perform any type of ls1 heads ported and polished? also are the valve sizes larger on the ls6 heads than on the ls1's?

stock LS6 heads will out perform stock LS1 heads, ported LS1 heads will out perform stock LS6 heads... both LS1 and LS6 heads come with the same sized valves 2.00 intake, and 1.55 exhaust

do some searches in the Internal Engine forum (if the search function is working), there is a TON of good info in there.

There are lots of vendors selling ported LS6 heads - as posted above - check out the internals section. Patriot Performance, Texas Speed, TEA & ETP to name a few.

Unless I'm mistaken, all LS6 heads should have the number 243 cast into the head outside the valvecover rail on the lower right side. LS2 heads use the same casting, but the valves are of course different.

well ive been told to go with the dual springs kit bc those cams are hard on valvetrain.

Our heads for $949.00 don't require a core, however if you have a core set of "243" heads, we will give you $300 for them. The $949.00 will be charged up front and once we receive and inspect the core heads, we'll give you $300 in return.

My bad - sounds like a good deal. It's amazing what you can find in 5 minutes of searching.
