yz426 cylinder head resurfaced

Recommended Posts

I resurfaced my cylinder heads at the machine shop at my local community college because they were warped. I took .008" off the second picture and .006" off the first picture. My question is can I take more off the second head because

its sill warped past service specs. how do I upload the pictures?

If you have your old head gasket, I'd bolt it up with some clay on the piston, install the cams and turn it over a time or two, then pull it off and check the valve to piston clearance. .014" is quite a bit, and I'm not sure what the resurfacing limit is.
