I changed to the Trickflow intake with stock heads and saw almost no gain on the GT. That was also a long time ago too.

im deff with usmc on this .i didnt read every ones post but the stock e7 heads are junk.the ports are small and the valves are small.the stock cam is small,the intake has small long runners which are good for bottom end power.if you put an intake on a on a stock set of heads you really wont see a gain,if u put a cam in a stock motor u wont notice much eaither.i ported a set of e7 heads with a b cam,1.7 rockers,edelbrock performer intake,373 gears,stock headers,bassani x pipe and flowmasters and a 150shot of spray and ran 11.8's. but the amount of time it takes port them or if u dont know how to port them the money you would waste for what u get is not worth it.basically between heads, intake,camshaft none of it works that good as far as performance,they work good togeather but,if u change the heads ur gonna want a cam and intake to match the flow of the heads .if every thing doesnt work togeather you wont get the full potential of the motor..any ways the biggest gain you willl recive on a stock motor will be a set of aluminum heads.the order i would put them in is : heads,cam,intake
