Piston to valve clearance How much do I need?
Looks like I need to mill the heads.
This is what I got.
Hand ported 5.3 Heads with LS6 sodium filled valves (flowed 291 int and 226 ext) These have not been milled at all.
6.0 Liter stock short block. I think it is the LQ4. It has dished pistons. Again the sort block is stock.
GM metal 6.0 liter gaskets.
Cam - 237/242 .603/.609 113LSA
