I have some fairly new looking cylinder heads i pulled off of a stockish 1600cc engine i recently tore down in order to build a stroker 2017cc motor. I cannot see any casting stamps or markings on these identifying them except for these two. Anybody know what brand or type they are? Are they a good candidate for port and polishing and valve job for a future smaller engine build?

They look like newer Chinese manufacture heads, IAP or Kuhltek come to mind.

*edit to add*
Take note of the etched markings near the exhaust port in the pic on their page: Kuhltek 041 head

What size are the valves? Typical 35.5mm intake and 32mm exhaust as per carbureted dual-port engines? If there are no cracks going from either valve to the spark plugs and the guides are held firmly in place by the press fit, IMO any dual-port head can benefit from mild to moderate port work and a 3-angle valve job.

In this article, the heads are those from fuel-injected Beetles with smaller valves than above, and had very minor work done to them. But in a later installment, the engine made surprisingly good power.
