4.8 heads should bump your compression up. Only thing is, in stock form the 4.8's heads will get outflowed by either 317's or 243's.

Not exactly, the LQ9 has the better flowing 317's v.s stock 4.8 heads. It achieves high compression due to flat top pistons. Either way you'll have more power than your 4.8 so you'll be alright.

I'd go ahead and put heads on now, head gaskets and bolts ain't cheap. But that's just me
