rookie sbc head question

I've got a question about a set of SBC heads. The casting number on the heads I have are 3973487. From doing a search on I found this..

3973487....71-72....350...used on 71-72 350 LT1, 75cc chamber

my question is does the LT1 mean these came on a performance engine (corvette)?

does anyone know what size the valves are or how can I find out?

Maybe I got lucky and got some good ones.
