ok so i have a 87 camaro with a 305 tbi that the person who had it before me screwed up and put a holley carb on it. i like carb dont have to worrie about all the electronics and wat not so i want to keep it that way. it has center bolt heads. performer intake and carb spacer. all the tbi wireing is sitting around and looks like **** (going to sort threw and get rid of wat i dont need) but i want to build my 305 a little but no clue about wat to do cam and head wise.. any ideas? thinking roller cam and lifters and rocker rollers cause its a rollor motor but dont know what to get and all that, as in durations and stuf. do i get the heads ported all that stuff. i can put it all together i just need help figuring out wat i need.thanks

There was no TBI in 1987, so something is wrong there - either the year model, or that it was TBI.

Pull a valve cover and get the casting # off of the heads. That will tell whether or not it makes any sense to put any effort into the heads.

ill do that when i get it back. it getting rust holes in the floor taken care of. but idk this car is a mess it has a reman tag on the bottom of the block. i bought it for 2 grand as a 350 with 411s got it home put the new intake on it found out it was a 305 popped off the rear cover found out it had stock gears. and the vin tag on the rad support was taken off and the when i look up the vin it comes back as a iroc and its not. so this car is all kinds of messed up. lol but ill let u know in a week or two when i take the valve covers off.
