I pulled the head off my car. I am checking valves to see if the seat correctly. I noticed that on cyl 4 & 3 intake valves, they open offset from each other. 1 Opens before the other and closes before the other by a little bit. Cyl 2 & 1 open evenly and close evenly. I spray brake cleaner in ports and let it sit for 10 minutes, no leaks. Is this normal? I am going to test exhaust side next.
Setup: BC 272cams, +1mm OS valves, BC springs/retianers 200 miles since valve job
