Sealed Power pistons

Thanks for the reply guys. I'm doing a 68 318. According to my old Chilton it's 230 hp @ 4400, 340 lbs-ft @ 2400, and 9.2:1 comp. stock with a 2BBL. I'm not building a race motor, just somthing that'll have power for a driver. It'll never see the track. Just cruising. So the KB 167's are the way to go? .030 over or stock? I'm keeping the stock heads, unless I run across a set of 302's soon. I'll be running the Comp Cams XE268H cam and springs, and an Edelbrock LD4B with a Holley 600, 8 3/4 w/ 3.23's (also have a set of 3.55's I may switch to) and a 4spd.
