need advice on stock vortec or hump heads (not one vs the other)

[ihatericeburners]

Im not asking which is better, but which is a better fit for my particular situation.

I have a stock (heads, cam, pistons) goodwrench 350 with a/c, p/s, dual plane intake, hei, 600 cfm Edelbrock, rebuilt auto 350, original gears, 20 inch wheels. She is just a cruiser but I want more usable power.

I have access to a set of hump heads. The 461 variety. With 202 valves, ported, polish in studs, new springs, hardened seats, bowled, that are said to have 10 hours run time. They are my fathers and he has $300 into them. They were purchased as is.

So my question is would the motor make better power on stock lift/rebuilt vortec heads with a low lift cam or woulf I get better power out of the hump heads and a higher lift cam. I would like to keep the heads and cam swap close to $600. if i go the vortec route i want to make sure the power will be significantly higher for the added cost of a new intake and covers.

I have never swapped heads or a cam but I have always wanted to learn. Its always been a little embarrassing when I say I am a classic truck fuy and have never been deeper than the valve covers! Lol
Thanks!
