porting Roush 200 heads?

i have a set of roush 200 iron heads from world products. i've been scratching my head for a long time if it's worth it to get these cleaned up and maybe a mild port job on them. the intake side seems fine on these just the exhaust side. anyone have these heads? and does anyone have any flow numbers for them ported? how much did the porting cost? i would like to keep them if i could just need to know how much a port job or cleanup would be and if it will be worth it, could save me a ton of money. thanks.

running on a 347 with gt40 intake(plan to port lower) 24lb. inj, fender cai, 255 fuel pump, custom chip, (getting new cam for sure) 3.73 gears

porting heads

i have some threads yes, at least you are observant. but i'm getting all the input i can get and i'm short on cash, but i would like to enjoy my car for the time being until i do have the money to do some real work to it. the more knowledge the better, and i'm trying my best to figure out if it's best for me to keep what i have for now and make it work better w/o spending mucho bucks. i love talking cars and this is the place to do it. if i have ?'s what better place to get input than somewhere where everyone deals with a lot of the same problems and obstacles you or i might have. you have any input?
