The advantage of running a thinner head gasket is if you somehow warp the head, you can mill the head, put in an OEM head gasket and still be at the same CR. Once you mill, you can't take it back.

 

i see your point to



power gains, head gasket alone whould be nothing, but whould help out other mods, like a good intake/header/testpipe/exhaust, with the hi comp headgasket whould be nice, and some nice gears, thats all id do if i had an S, plus while your in there arp headstuds and arp rod bolts, and youv got a nice strong motor you can beat on

 

with a few other mods it'd be a nice n safe increase in power, from there it's in the tune.

Only other thing I'd add is a warped head MIGHT be fixed....it all comes down to how bad the warping is. good info in here though.

 

Of course.

 

NASA Performance Touring rules allow the use of an offset key on the crank pulley to realign the timing to stock specs. I saw no such provision in the TT rules. If I have the budget, I might tinker with it to see if there is any use in messing with this timing (within the rules, of course ). I suspect the impact of such changes will be within the margin of error of most dyno measurements, so it probably won't be worthwhile for the level at which I'd be competing.
