For a look at all the gear you'll be lusting after this year, stay tuned to the 5.0&SF blogspot, and for today's installment of what we spied at last year's SEMA show, check out the full details after the jump...

All-out racers who can’t keep their heads on will be interested in World Products [(631) 981-1918; www.worldcastings.com] new six-bolt, Man-O-War, 10-degree small-block heads. Two extra head stud holes per cylinder help withstand blowers and nitrous, while huge 2.250x1.625-inch valves and equally voluminous 255 and 275cc intake ports show this is a pure race piece. Heads are sold bare or complete, including Manley stainless steel valves and ARP hardware.

If you need a six-bolt block to go under these heads, World Products has its existing cast-iron Man-O-War block to suit, along with a new aluminum version; it features the extensive strengthening and oiling improvements associated with these championship blocks, along with optional main bearing sizes, 8.2 or 9.5-inch deck heights, and more. Going the other direction, World also announced a new 18-degree small-block head—with four-bolt retention. Runner volume is 200 or 235cc with 2.055x1.600-inch or 2.100x1.625-inch valves. The chambers are all 64cc; valve lifts to 0.700-inch are accommodated.
