The 2nd Link I Read Grumpy.
Valve job tech info always worthwhile reading.
Every shop does it thier own way.
I am one of the few Hotrodders with my own valvejob equipment .
Seat widths always a debate for race and street .
I still like Interference angles.
Almost 30,000 miles since I fixed the wifes Honda CRV . Valvejob by me & Ferrea Super Alloy valves installed.
Still hitting like brand new. 230,000 miles now.
