It doesnt cost a lot to o-ring them. Problem is once you do that are worthless to just about anyone so I like to make sure its going to help on these. i would rather o-ring the block, but I dont know if you can with LS block. I have had plenty of o-ringed heads/blocks with copper gaskets but years ago when I tried O-rings with steel shim gaskets on my nitrous SBCs I never had much luck.
I just havent heard of a lot of people doing this on LSx engines with MLS gaskets, I have no problem doing it if it solves the problem. So besides mike who is making a crapload of passes at 20+ pci with an LS1 with o-ringed heads and MLS gaskets?

i've been also looking at that class, and the heads limited to 221 max(ported or as cast), are you planning on a different head then you run now?

only 'legal' aftermarket casting is the AFR 205 and I have no idea how they measure CC wise out of the box and if they can be opened up a little more.
The dart 225s actually measure in the low 230s but I think even a decently ported set of LS2 heads with good valves at arounf 218cc would be just fine. I woudnt be the fastest car but could qualify in the top half no probllem I think. Just looking for something to do and that class fits mt car pretty well.

Then again I may just be lazy and run the new EFI index class, it goes down to 9.50 and it will be just LS1 cars, SN mustangs and the new hemi cars. If they have the same paout as open comp with contingencies its a better deal really since I can leave what I have on it..
hmmmmm. this is really tempting me to oring the heads. damn, there are so many routes to go, and for each one, there are good and bad cases. i wish there was one, clear cut answer here. i keep getting different answers

I wouldnt be trying that very often
14psi. with the cutoff closed, so it was down to about 11 psi well before redline. i really cant explain my mph....but it makes me smile. woulda been 145 if i had the gear. the engines apart, and i was told there was no signs of det, which doesnt necessarily mean it definitely wasn't, but just passing along my info
