22r/22re Nippon Racing cylinder head review

[xLOCOx]

Hey there guys, just thought I'd wack up a review of this cylinder head, just arrived today,
Came in a decent cardboard box, wouldn't have hurt to put some fragile stickers on :/
But the machining quality is pretty decent, obviously the hole head needs a degrease and blow out before assembling, did find one singular alloy chip sitting in one of the coolant passages,
Casting quality looks pretty sweet, not too much crud from left after machiningand or the casting procedure,
Valve guides have a bit of schmooze in them,
The Japanese writing in the first pic actually translates to Nippon Laceing parts made in Japan? Using google translater,
I've marked the intake side of the head ready for port matching so excuse the blue marker, hahha
The valve seat insert has a sharp edge on the exhaust side in the port, nothing a dremel won't fix, then I'll get the seats recut once I have the new o/s SS valves, well, when the pocket lets me, hahah

Little update on the cylinder head, light port matching and polishing the exhuast side, only pic i grabbed last night was of No.4 cyl exhaust, im sure i could work on it more to get it better but im finding some voids/air pocket in the cast, VERY miniscule, i still cant complain over the price,

pic below focused on mid throat of port.
