Default Nitrous with 11 or 11.5:1 compression?

I am putting some new heads on this weekend and they are the TEA stage 2 5.3's with 62 cc chambers.. should put me around 11 or 11.5:1 compression.. I was just wondering for in the long run.. what would be a safe shot to run on my car? Would a wet kit be alright spraying a 50-100 shot? I don't wanna be to hard on my stock bottom end.. Anyone spraying with a similar set up?

I'm not looking to spray a lot.. just a safe shot to gain a little mroe power when i need it

Thanks

Put some NGK TR6 plugs in it. Buy the Timing Tuner from Tbyrne. It is a plug and play system so you can retart the timing. I would pull 2-4 degrees back for the 100 shot. Run 100 octane gas in it to be on the safe side.

Alright cool... would stock GM head gaskets hold the 11.5 compression with a 50-100 shot of nitrous with a timing tuner, TR6's, and 100 octane gas? or would i definately need some aftermarket stronger head gaskets?

I'd still of course buy all of the safety equipment for the kit.. like the Fuel pressure safety switch and a new intank pump..

I'll definately throw one on over winter as long as the GM head gaskets can hold all of that pressure? Let me know! Thanks

I'm spraying a 150 dry shot thru my 11.5:1 346 cid motor, with 205s and max spark advance at 22 degrees.

awesome! i'm probabaly going to save for it over winter and have it on for spring so i can shoot for a 10 sec time slip..

The only concern was having the stock GM head gaskets on and not some $90 a piece aftermarket gaskets.. Is that not a big deal? Thanks for the replies!

I would just stick with the stock GM MLS gasket. I made 648rwhp 700rwtq with no issues useing those gaskets. I also used ARP head studs im sure that makes a differance. That was a 225shot btw, on a stock bottom end.

Mine is pushing 11:1 and I spray 100 shot TNT on pump gas all the time. I run 24* of timing and TR-6 plugs. And I also have GM MLS head gaskets. You'll be fine as long as your tune is on and your fuel system is up to the whole packages needs.
