Procharger or turbo on 6.0 Ok so I plan on doin a 6.0 swap into a old school chevy truck. I haven't made up my mind on a lq4 or lq9. And I wanted to run 243 head p&p but they say u want lower compression for boost. I just want yalls opinion on wht built I should do and wht setup as far as heads and everything. My truck is goin to be a daily driver so I want it to run on pump gas. Thanks.

The LQ4 has a lower CR than the LQ9 due to there dished pistons. The 317 heads that come on both engines flow the same as your 243s and also have larger combustion chambers (72cc). I'd go with a lq4 with the stock 317 heads. Also get yourself some good head gaskets and arp head studs.

no you dont need to port them. Stiffer valve springs and hardend push rods would be a good idea though. Most guys seem to be running ls9 head gaskets (ZR1 head gaskets).
