Do I need this heads? Tell me if they look good...

[oldblue1968chevy]

Going to build a motor for my truck someday and Im collecting parts. Found some heads. They were 'redone' at some time. (20 Years..lol) never been on a motor. They have 'the big valves' '4barrel heads'. Are they somthing I should put on my budget 350 build? Im looking to spend NO MORE than 1000-1300 dollars.

So far Ive found myself

4bolt main block no machine work yet
edelbrock high rise alum. intake (not sure exactly what type)
500cfm carb. (just rebuild may try to find somebody to trade for slightly larger holly or edlebrock.
still undecided on the rest
I THINk I have a steel crank, how can I tell (was told it was out of BIG truck)

He's also got some heads just like em(too lazy to run #'s) but I can.

there not 'redone' yet he said he'll trade me for my extra qjet carb.

good trade what should I do

He wants $150 for worked heads (ones pictured)
