P-51 push rod length- help really dumb question

I have a really dumb question but I'm going to ask it anyway because I'm old and forgetful. I have P-51 heads and I run 9.100" and 9.300" push rods. Well I mixed them up the other night and I don't remember which ones are exhaust and which are intake. I think my intakes are the 9.100" and the exhaust is 9.300" but can anyone back me up on that? Are the intakes typically shorter? Thanks.

Long ones on the exhaust.

Thanks that's what I had in my notes but I didn't trust myself.  

You would have known as soon as you rolled the engine over and watched the roller on the valve tips. There's never a dumb ? when unsure about anything.

The exhaust is the farthest from the lifters also. You can see if you look, it needs to be the longest. You wont notice it until you make a point to look at it.
