Autozone lists 2 different head gaskets for the 460 in '86.

Would the (built from 2/21/1986) be the fuel injected motor?

I have a non-fuel injected engine and plan to reinstall my heads. I removed the heads to check the condition of the pistons and cylinder walls since I just bought the motor.

Thank you

 

That would be my guess but why not call Summit and see what they list or do it on line. I ran into that problem when looking for parts for my 88 moter moter home. The bookes showed it to be injected but it wasen't. The chassey was made in 87 but not compleated/built as a MH till 88.

My '87 is still carburetated.
Motor homes and other chassis/industrial engines until '89.

The 520SD has a steel core.....
