Thanks. His case is an extreme use of the head. He is limited by class. It is an excellent use of the head.
Now let’s do similar to an aluminum head.
"I had a stock crank .04 overbored 360 in the Demon that went 10.25 at 129.99 mph. Ported 587 heads,.590 racer brown flat tappet cam, victor 340 intake, crane gold 1.6 rockers, 11.75 to 1 comp ratio. Motor in car now is a .04 over 360/ w a 4.100 stroke crank, [418 c.1.]. Still has the racer brown .590 cam and ported 587 heads, a little adtnl. work to heads, flat top piston out of the hole .080, 13 to 1 comp ratio, Victor 340 intake, Crane 1.6 rockers. Burns 110 octane race gas or would be fully streetable. Never over 190 degrees even when it's near 100 deg. outside. Has gone as fast as 9.68 at 135 mph and as far as 450 ft on the rear wheels. Definetly over 400 to 500 horse . Not to shabby for a junkyard headed small block in a car that weighs 3060lbs. I never recall seeing a brand X sm block w/ junkyard heads anywhere near my e.t. at or near 3060lbs. I chase alcohol burning, roller cammed, aluminum headed sm block chevys all the time."
