3 angle valve grind?


Recommended Posts

i've had to buy a new head for my ea82t and am getting the valves matched. Both heads are apart and wondering if i should get a 3 angle valve grind done? I know it does wonders on small block chevy's, but i don't know about on subes. anyone ever done this?

I figured a three angle grind is pretty much standard operating procedure at the machine shop...unless it's a real high performance engine and a 5 angle grind is best.

 

just cutting one angle on the seat is kind of bogus. A three angle grind generally helps airflow around the seat when the valve is open, and you can adjust where on the valve the actual seating is taking place.

 

To answer your question, yes. Competent machine shop?
