Swapping heads sbc

Alright guys, first this a 350 30 over motor with an xe268 cam aluminum intake and a 650 edelbrock. problems with my double humps is causing me to have to put a set of stock 882 heads. The double humps were 2.02 valves and also shaved to 60 cc. I was running the .015 head gasket to raise compression a little more. Now the 882 is bare stock. not sure what the chamber size is, they came off of somewhere around a 80 model truck. Just wondering what performance changes i will see, and if there's anything i can do to help before i put these on the motor. thanks guys

Cliff Ruggles said do not run 882 heads . He recommended 993, 336, 441, or 487 using a Felpro .035 gasket when I talked to him . He has been racing and building engines for 30 plus years .

I understand they aren't the right choice when you have the option but i don't have the money to buy new heads at this time, and no one can seem to tell me how to fix the double humps i have. I just want to know how to make the best of what i have for now until i can buy new heads.

the 441s would be great because i already have them but one of the rockers is trying to turn sideways for some reason. I guess when i pull them off i could take them to the machine shop and see whats wrong, i just hate to really dump a lot of money in these heads. if its not a really simple fix i'd rather slap the 882s on for now and save up for some dart heads
