I had coolant in the number 3 cylinder. I'm not sure yet if it was a blown head gasket or a cracked head. I've got the head off now and I cleaned up the number 3 combustion chamber with a plumber's wire fitting brush on a drill. I can't see any cracks, of course I understand that doesn't mean anything. It should be magnafluxed.
My question is... The valve seats on a 261 Chevy, are they inserted, or are they just cut into the cast? I've worked on mostly aluminum heads all my life, Honda motorcycles, etc, etc. And they have the seats inserted of a diferent material.
I have pictures of my project in my photobucket
Thanks in advance for any replys
