TEA LS6 Stage 2
TEA LS6 Stage 2 Just ordered a set of these last week and they came in today. These cylinder heads look amazing and Mike from TEA was awesome to deal with. I wanted to post up flow numbers for those that might be interested as I was a little surprised. Hope they make good power, my new setup will be done about two months and I'll update with dyno numbers and track numbers. Going to these from a ported set of 853s Hopefully they'll make a noticeable difference. These are 62cc's. How much was taken off from milling was not listed on the paperwork, but I believe that it was .025 from talking to Mike last week. Anyhow, here are the flow numbers...
Intake
.100--70.1
.200--139.7
.300--216.1
.400--269.9
.500--309.7
.550--319.3
.600--326.1
Exhaust
.100--59.0
.200--121.5
.300--181.5
.400--240.3
.500--261.6
.550--267.7

For some reason their exhaust numbers are always jacked up (mine too) so not sure how to explain it....... even when I see them flowed with a pipe TEA #'s seem high...
Congrats they are the cream of 243's with only 2-3 others IMO....

Are you running this on 3.9'' bore or 4.0'' ?
If 3.9'' , which head gasket is required to use with these heads?
I know people have used 4.0" bore head gasket on their LS1 due to the big intake/exhaust valves.
Nice choice , congrats .

Stock LS1 gaskets or Cometics can be used for a 3.9" bore I would think. I don't know for sure how large you can go. Plenty back in the day use to use the 2.055 valves with stock gaskets IIRC
