Milling 243 heads w/ nitrous???

I'm having a set of 243 heads worked over this winter. My plan is to have them milled .030" and use stock .051" gaskets. Should put my CR around 11.2:1.

I've been toying with the idea of spraying the car, but I want to know if my deck height will be too thin to spray.

What is the deck height limit when using nitrous? When do I need to go from bolts to studs?

Educate me please...

I'm in the same boat....but so far no one around town has said anything other than to spray the hell out of it. Will see I guess.

N2O can be used with compression ratios as low as 9.5:1 and as high as 15:1 its all about the set up. What you have to make sure is that you are using the correct equipment. Like ARP Studs/bolts. Also that your fuel is correct and you are running the correct timing. Many cars have milled .030 and are using N2O.

Good Luck

Yeah, that kinda seems like a Ft. Wayne thing haha. I've gotten some decent feedback on ls1gto since I'm a n00b when it comes to spray. Any bites on your car yet?
