If you want to do more, spend about two hours opening up the exhaust valve throat to 90 percent of the exhaust valve diameter (1.5 x 0.90 = 1.35-inch diameter). Stock cams produce relatively low lift, so the back cut will improve flow in that area. To keep the price down, have your machine shop perform a 30-degree back cut to the intake and exhaust valves. This gets expensive because you still have to purchase a set of Vortec heads, so we'll concentrate on retaining the stock heads for budget reasons. The intake is PN 12496821 ($370 from Scoggin-Dickey). There are ways around that by using a GM Performance Parts aluminum intake that bolts to the Vortec heads and features a stock mount for the TBI. However, the Vortec heads use a different intake bolt pattern that does not match up to the TBI intake manifold. These heads flow very well and would be a good choice to make 300 hp with a mild camshaft. The best approach would be to go with a stock camshaft and a set of Vortec iron heads.
