My issue with the 162's are high pin, large valve reliefs, and if it's a performance build there's a very honest chance somewhere down the line the idea of throwing some squeeze in the mix might just come along... Nitrous and hypers is a no-no. Plus they're fragile, easy enough to knock the top land off with detonation. Just better choices... You can change a engine around pretty easy but piston, rods and crank selection are pretty much married to the initial build. Choose wisely.
