Need headgasket recommendation for 355 TNT setup

Well...we finished installing the kit on Saturday, blew the headgasket on Sat. night and now I'm in the market for a new set. We know what caused it....about 39 degrees of advance

Were getting it put back together now but I'm wondering which headgasket would be a good choice for N2O. Impalla gasket, LT4 gasket, stock gasket??? Before I went to N2O I was planning on the thinnest I could get my hands on to bump up the compression for better N/A times but now that I've turned to the bottle and need a little voice of experience to lend a hand.

Thanks for any help you can give.

fel pro 1074. are you using arp head studs or bolts?

Thanks man...I found the info a couple days back and picked up a set of the 1074s. We put it all back together this morning. I am using ARP bolts for the heads and intake as well as other places.

Thanks.
