Question cam change

I am in the middle of a cam swap on teh wifes car. I am using air to hold up the valves, what PSI. should the regulator on the Air compressor be set to to hold the valves up.....I guess the more pressure the better....I guess what I am asking is what is the minimum?

I just used the pressure listed in the LS1howto.com which was 60-80 psi. I used 70 when I did my cam swap and everything went fine. Good luck on the swap.

but you have that little bit that the valve will move, and thats kind of a pain in the ***. at least that has been my experience. the air pressure bleeds off pretty quick while im doing mine, so ive unfortunately let it get done to about 45 psi, but it wasnt a prob, they held. i would say 60-80 though
