I need some advice here folks.
I'm rebuilding a 310.
I had the valve seats ground after i replaced the guides.
When i was lapping the exhaust valves i saw that the seats are not what i thought they should look like.
The seat width on the narrow spot(there is no meat left underneath that spot as the exhaust bore slants away at that point) is only 0.0375"...this is on all exaust valves that way.
Have a look and tell me what you think
