| Yeah I thought that was weird to about ww because they sell the okrasa 33/30 valves and springs retainers and locks but no valve seats lol you would think they would carry them but nope and like most places they don't wanna get them from their supplier who build their heads for them which again is weird since their buying all the other valve train parts for their head crazy .... |

I had the same problem last year. So, I found 32 mm seats. I talked to the machinist doing the work about the problem. He said because it was intake not exhaust it may work. As the valve will sit lower in the head it won't be affected as much because cold air and fuel are passing by it, not hot as an exhaust valve. I was concerned about the valve stem height. So I put a straight edge across the tops. It didn't make enough difference to be worried about. I have not put my engine together yet but I can post pictures if needed/wanted.
Stock 36 HP head the on left. 36 HP Head with Okrasa intake valves on the right. As I could not find 33 mm intake seats, 32 mm seats were used.

Are these for Okrasa heads, or are you putting Okrasa size valves in stock heads?
I was told by someone who is no longer around, that you could usually install Okrasa intakes on stock seats. He said you had to port the ID larger, and that there was just enough meat left to cut the valve seat. Not sure what the repercussions of doing it this way is, or if you can do the exhaust the same way..

I bought custom valve seats from US Seal for my custom sized stainless Stainless valves on my Single port heads and had them installed at a local machine shop. cheap at couple bucks a piece, but the cost to install them was quite a bit.
