If you have the heads off then the small valve will be the exhaust.
Now if the heads are still on the block then remove the valve cover and look at the valve springs. Starting at the front of the head and moving towards the rear the valves will be in this order. E I I E E I I E The E stands for exhaust and the I stands for intake.

Where do you find out what size engine you have on the block it is a Chevy don't know if it is a smaLL Or big block?
Chevy does not cast the block size onto the block. once you see a big block compared small block you will know the difference. at a glance with nothing to compare it to id say look at the head. small block heads have one exhaust port close the ends and two exhaust ports real close together in the middle. the big blocks exhaust ports are evenly spaced and not close together at all.
