I have my cylinder head off because of low compression .

When I shine a light on the cylinder side of the valve and look into the exhaust I can see light through the tiny crack around the valve.

I can tell that the seats on the cylinder head are worn. But I bought new valves and I still have the small crack.

My question is should I regrind the seats or can I get away with just lapping it with the lapping compound?

 

re-grind the seats

 

I think you're right. I am going to take it somewhere to get it resurfaced professionally. Im thinking I'll probably ruin them more. ughhh

Anybody know a good cheap place to get seats resurfaced so-cal to central cali? ~ Im in bakersfield area.
