I just bought a set of gt-40 irons from Randy (thanks randy they just got here and look good) I was wondering how much horsepower would you all guess I would gain from installing these heads with the stock cam?? I would say they are mildly to mediumly (spelling lol) ported..my other mods and dyno numbers are in the sig...can I get 25-30 rwhp? I am just starting college and it will be a lot longer wait time to save up for the cam and install and I am not sure I want a cam anyway it being a dd...I mean it could be 6 months wait if I want to get a cam whereas without the cam I could prolly install next month...so just wondering can I get 25-30 rwhp from the heads on stock cam? that would put me at 265-270 which I would certainly be pleased with...
