Something let loose in the topend of my lq4. It's 4 door HD so not really looking to go all out for speed but more torque would be nice. I have a rebuilt lq4 replacement ready to go in. Anything I should take care of before the motor goes in? I have new Valve cover gaskets and grommets Cam sensor Crank sensor Oil pressure sensor Front main seal Rear main seal Oil pan pickup oring Oil pan gasket Arp manifold bolts Exhaust manifold gaskets Collector studs and gaskets Knock sensors and intake gaskets were done earlier and will come over from my current engine. What about the steam line kits, is that something to look at or more for race? Cam and valve springs?
