They pop up quite regularly on CL, ebay, kijiji etc too, and of course the buy, sell or swap groups if you're on FarceBook.

Correct me if I am wrong but all 186,s are not 2.02 valves.

No, they aren't.   Some '186' heads were ground/prepared for 1.94" Intake valves..   In fact, in searching for these old heads these days, one might even PREFER to find the 1.94" valve versions for prepping for 2.02 usage...  It allows cutting away from metal to get to fresh metal and maybe eliminate some cracking of the seats.   And Yes, the combustion chamber will need some work to match the 2.02 factory shape...

There is a previous post concerning cutting 1.94,s out to 2.02. Many opinions either way. Just saying watch ebay ads. Many do not say what size.
