Might want to little more digging before you order, the 2 springs at the bottom are for a 350. You can't run 120lbs on a quad valve.(you'll pound the seats out of it)
Maybe check it with the lunati site comparing the part numbers. I know last spring a part number for .620 lift cam was found (at advance) for the 2.3...........

I did a little checking, I think you found some V-8 stuff the springs(at eh bottom of the page) are to big/stiff to be quad stuff, atleast 1 of the kits use that same spring part#.
I did check lunati's site, no listing for 2.3,quad 4 etc.
If I looked it up by car I came up with some 355 V8 stuff for the beretta

I run 115 seat pressure and 230 wide open on an ecotec ..... so why cant you run that kind of pressure on a quad?

you run 115 on a eco? WOW, a HO is only 85 stock, the drop in racing ones(good luck finding) are 100lbs and are for .100 long valves,
the big killer on seat presure is usally it ramp up to 300+lbs (like you noted) then when closing it pounds the seat. so massive pressure on the way up will swipe a cam, and massive closing force can kill the seats or suck the valves in( i have pounded the seats out with to much pressure)
