TRW actually says the reliefs are 7cc.

Hmmmm...I wonder if I could get away with cutting the heads and still have enough clearance. Guess I could always cut them and bolt them up without gasket to see what the p-to-v clearance is and then figure out what to do then.

Would cutting the heads .040 mean my ptv clearances would become .080" intake (.120"-.040") and .134" exhaust (.174"-.040")?
