I am in the process of making a 383 Direct Port Nitrous LT1, my question is until I get the money to port out the heads and put new springs, retainers, valves and everything else that you could possibly be done to make the head stronger. Can I shoot a 150, maybe 200 shot of nitrous on the stock heads as long as I don't go past redline. For some reason I thought I read that the components in the head wore out or float only by going past redline. I will probably have to get some arp studs to hold the head down though, right? Thanks for any help.

 

Run as much blow as your bottom end will take. Or as much as you have the nuts for. Its just like NA, dont rev it too far and your fine.

Go ahead and get ARP studs, you'll be using them eventually anyway correct?
