Default Clamping force in question !

Just sent my LQ9 block and 317 heads to the machine shop. Getting double o-ringed and 1/2" studs installed. My question is how bullet proof is this combo?? A friend of mine has the same block and head work as I described and he's 13.5:1 and spraying 500hp with a plate and fogger system. I have know idea what his cylinder pressures are but they gotta be high. He's never lifted a head or pushed water so I'm feeling pretty confident. I'm going forged 370 with either S88 or F1. So I'm wondering about lifting a head, the PSI will be pushed pretty high. The compressor maps will hold atleast 30psi, so anybody got experiance or input on this setup ???? Thanks in advance..

sorry I cant answer your question but what does it cost to have it o-ringed and tapped out to a bigger stud?

My machinist is charging $200 for the heads and $200 for the block(o-ring).
And the stud work is $250. I consider it all to be very reasonable.

Sorry another cant give you a answer, but I noticed you were in Tulsa. I've been looking for a machinist. Have any advice?

Also we go down to the track every now and then. Ive never seen a setup run like your friends. Not saying it hasn't ran when I wasn't there, but I was wondering what it was so I know what to look for. 500 shot sounds fun!

Be there (Tulsa Raceway Park) the 16th and you will see him. Ever heard of Oklahoma trueten five ?? Here's the site; www.oktrueten5.com there also the Mako series; www.makotenfive.com. And as far as machinist go, Stanley Morton in Broken Arrow is a serious engine builder. He's built several of the engines in these classes. (Morton Machine)

Name of machine shop? That is CHEAP to have a block o-ringed and being in Kansas that may be a route to have done compared to other prices
