Started lapping in the valves today in my 243 heads. I also replace valve stem seals and added the GM performance valve springs that go with the LS6 cam.

The drive by wire gas pedal is done. I modified the one that came from the 03 Yukon when I bought the 5.3L. I used the original S10 pedal and merged it with the Yukon.
Test fit.

My block is back from the machine shop. I painted it GM satin black and I put the LS6 cam in with Melling timing chain guide.

Crank is in and torqued and put new barbell in oil gallery. Tomorrow off to the fun task of gapping all 32 rings and installing the Pistons.

Pistons and rings are gapped for nitrous rods torqued with ARP bolts. I checked the Piston to deck clearance it changed my compression ratio to 10.6.1 I was shooting for 10.5.1 but I guess it's better to have a little over than under. Oil pumps in pickup is installed with ict billet hold down where it has two bolts.

Are you planning on racing it? Drag or track? Or just want power under the hood?
