317 heads + 15 psi = o-ring?
Hey guys
If i want to run stock 317 heads over 15 psi boost, will o-ringing the block provide adequate clamping? Dont really want to pop for new heads now, but o-ringing the block seems cheap enough.... id like 800 motor hp now, but may want to increase later...
thoughts?

Nothing is a "guarantee" in this game. For 800 flywheel horse, oringing shouldn't be necessary with a good tune. Several people here run up to 20lbs with just good gaskets and ARP studs. Oringing does help as the boost pressures go up, but for your goals you should be fine without it.

We used some off brand company's studs torqued to 100lbs on the nova I speak of. But Honestly I think they were crying when we did it. Did not feel solid.
I believe it takes that much torque to keep the heads down then one probably should be lookin at other options lol
