Default 6.2l headgaskets

I read a few posts before about these new gaskets being of a better design, anyone have any results from them?

I have only been to the track once so I dont know yet how they will hold up. Be a while before I put some decent boost to it but so far running 5.90 in the 1/8 they are fine. Going to hit the 1/4 this weekend maybe and see if I can run 8s with the D1SC so we'll see how they hold up.

4.100 or so, I didnt measure them myself but thats what others say. Since a 6.2 is 4.065 stock I assume its right.

There is talk of them in another thread.....

Yes, 4.10"

I made about 20-25 pulls on the dyno on mine recently, pretty much all of them above 800rwhp.

Cooling system pressure never exceeded 5psi, and when I stripped the engine after ( ring problems ) both head and block surface show no signs whatsoever of any leakage.
Engine has circa 1000 miles on it when I took it apart, all easy miles aside from the dyno.

I tried the search but it only works when it wants to, plus I was wanting to see if anyone had leaned on them yet. Whats the science behind head gasket sizing? I was wanting to try these out on my 3.905 bore engine with 6.0l heads, so the gasket bore has a larger opening then my heads and cylinder.

Im using TFS 225cc heads on a 3.905 bore.

The chambers/gaskets do overlap my bore.

only issue with those gaskets, on an LS2 block, they fit very sloppy on the dowel pins, almost .030" play.

When I fitted the 6.2 gaskets to my LS6/3.905 at the weekend, yes they are a little sloppy.

Although the dowel hole measures exactly the same as the 6.0 gasket.

Dont have a 5.7 gasket handy to measure it.....well, not a factory one I think. Given the mismatch between bore and head, I dont think the slop is such an issue.
