"dug in pretty good doesn't mean much of anything, I've had 4 cylinders that "dug in pretty good". To identify your heads pop the valve cover off and get the casting number off the heads, that's easy enough. To identify the crank you can try measuring through a spark plug hole or seeing if your local track has a "whistler". You should also check the block casting numbers as it could be a 305. BTW, there's nothing wrong with a 305, its just not as nice as a 350.
Since it sat a while I'd change the oil and throw a bottle of MMO in the crank case, then throw a can of sea foam in the gas tank. Doing those two simple things will help freshen it up a lot from sitting.
