Default 305 Cylinder Heads

So i am lookin at some new heads for my 76 camaro with a 305 not sure what would be a good head to get i want alot of power but only lookin to spend around $400 for the heads... Anyone have any ideas...i have the original intake manifold on and i am spending almost $500 on the exhaust which consist of hooker comp headers X pipe and flowmaster 40 series with dumps so their will not be much pipe on it

I would take the stock heads off and take them to a good machine shop to have the valves and seats replaced. My machine shop makes 1.94 heads from the wimpy 305 stock heads for $300. That's all new hardened seats, new valves and guides, which will make them flow extremely well and give you cheap HP.
Of course the real HP gain on a 305 is to do this head/valve conversion and also install a good cam and intake. The lowly 195 hp 305 can get about 350-375 hp with theses changes.

I highly suggest that you upgrade to a 350 in the future.

Yeah you have to have them lined up, heres a video to watch, it might help. But like Vall said, i would put a new cam in it to so whatever you do to your heads the cam can work with it.

I couldnt tell you what to get but im sure you'll have a better idea what to get once you get your heads done. You prob dont want something to big if your using those same 111k pistons.

I am definetly not an expert but i would get something like a ´85, 416 hads, maybe some new valves 1.94, 1.6 and 268H cam, headers, I did this with a 79 350, came out pretty good, not the best but it was cheap, I can only guess it´ll work fine for a 305
