I have a 77 camaro with 305cidV8. I was given a set of 327 heads ported and polished w/ 202int, 160exh valves, matching intake manifold, cam,and carb. After I have installed everything, any opinions on how much horsepower, i will have gained.

Zero hp gain, in fact you'll loose all power. You can't use those heads on a 305, the intake valves are going to hit the cylinder bore and the engine won't run.

ouch thats gotta suck

"he was denied like you get denied by the ladies"

Ok, lets say i replace the 305 w a stock 350 shortblock

Then sell the heads you got, and have a set of 350 heads p&p'd.
