look at this picture i made... tell me what u guys think..

 

you are correct. bigger valve holes and reliefs are for the intake

 

damn... I have my pistons installed the wrong way.. i should've followed my instinct.. can anyone please give more input? thnx..
i will more than likely be flipping my pistons around.. aswell as the connecting rods..

(i am in the middle of a build)

 

intake valves are bigger hence the bigger pockets and less gap.

 

update.. Arias has their logo under the intake side. =D ...
