my heads on a 84 gt
 

where do i find the numbers to identify my heads and what numbers mean what heads and which heads are best for my rebuild

Just look for the casting numbers for now, we'll help you out from there. I'm GUESSING you're looking for a number that starts "E3--"

Should be inbetween #1 and #2 (or #7 and #8, depending on which side you're looking at) spark plug, or under the valve cover.

okay the numbers under the valve cover on the drivers side says 3l4 but what does this mean????
