Cylinder head question

I am looking for a spare cylinder head for my 90-91 K5, there are 3 on eBay now. In the pictures provide in the listing, they appear to be all different weights? Can some shed some light on this?

I found 5 that would fit.
3 I would consider.
These first two I would pass on unless I was going to re-cut them.
This one is beat bad and needs to be re-cut.

This one is dinked up and should also be re-cut

This one is polished externally and likely has been shaved for higher compression which is likely the weight difference.

This one has also likely been shaved for higher compression which again would be shown in the weight difference:

This one weighs the most and is likely not shaved or is shaved the least.

The four stroke engine: That's one stroke for producing power and three for wearing the engine out.

Thank you! I should have mentioned that I wanted a spare head to get a decompression installed, Any rough est on how much machining on the head would cost? those heads prices range from $119 vs $150

Ask Larry Wiechman or Tom at Tom Morgan Racing.
