Your block is an 80-85 350. Without suffix codes, there's no way to know exactly what it was from. Get the stamped numbers from a pad in front of the passenger side head.
The heads were common on 79-85 350 engines. They're large chamber smog heads and probably have the small 1.94/1.50 valves in them.

FSM = ??? I can't find that code anywhere. Are you sure that's what they are?
The letters are usually hard to read.

I have them exact heads, the 462624's. They have that odd "camel hump" design. Stephen, if you're still subscribed to this thread, do you know of any decent, complete heads that would be nearly a bolt on replacement? I was looking at Edelbrock, but I've never had any experience with them. Maybe it's just a default type picture, but their exhaust ports don't match.
I'm about 92% sure my heads are also cracked. I'm going to have to invest in new heads soon.

Just about any aftermarket head will do. A good junkyard head to grab is from a Vortec engine. I just sold a set from a 350 medium duty truck for $200 that were given to me I had no use for SBC parts and $200 was a very good deal price.
