MF 135 AD3-152 Head Specs & Gasket

Cass · Apr 2, 2019

On my MF 135 AD3-152 I had the Cylinder head skimmed. The tolerance allows it to be 2.988-3" mine is now right at 2.975". If my engine block has the 0.013 of tolerance left before it is out of spec can I run as is ?
If not does anyone know where to get a oversized head gasket for this engine ?

Long as the VALVES face are in spec to the head surface DON'T put in a thicker head gasket. A thicker gasket will lower compression, which will hurt cold starting.

Do I need to worry about the thinning of the water jacket or will thirteen thous not make a difference ?

Don't worry about it, I've never seen one fail yet cut like yours. Main reason some engines have thicker head gaskets available is for cutting the BLOCK deck, NOT the head..
