Depending on how much the heads are for your car an how much you can get a used set for i would go an buy a good working used set an port them an try them out on the car an keep your good one incase that one doesn't work to right.
 
i have a 305 with stock 1.95/2.00 heads, and i have a set of 2.02/1.98 straight plug fuelie heads, so i'll test oin my stock heads and if it does anything then i will port my fuelie heads, ive had an idea ive named "turbo porting" which involves kutting a helix into the runners to increase intake velocity but i would rather test that on a flow bench
 
indeed, all on street tires, im looking for my thread entitled 'What Do You Drive?" so i kan post some pics of it for you to check it, its the OG of what you drive, its a 82 firebird
