Who on here is running an O-ring in their block? Do most guys running big power with nitrous and such and racing run them? My engine builder called me yesterday and wasn't sure if i wanted the my R302 block O-ringed or not. I told him no, but then he was like are you sure? Should i have the it done. I do plan on putting out some huge numbers and running in the 18-20 lbs. of boost range. I have always been under the impression that o-ringing was a bad idea as you would rather have a head gasket let loose than a piston. Heads are still at TEA as well, should they be cut as well?? Need to know ASAP. The car is goin to be street/strip as well, with a ton of track time.
