hey guys, just gathering parts for my rebuild. i was wondering if anyone has used the brian crower valves for the 1jz? i'm questioning their information on their site though... they have a listing for the 1jz 2jz and 2jzgte and they list the same diameter valves for all of the cyl heads. i was under the impression that the 1jz had 32mm intake valves vs the 33.6 mm valves on the 2jz and 30mm exhaust valves on the 1jz vs the 29mm 2jz valves... is this true? i don't have a micrometer on hand right now otherwise i would measure my own 1jz valves as they are out of the cylinder head right now. any info would be helpful. i have already emailed brian crower about this issue and will post their reply here. thanks!

still waiting on their response but can anyone verify that the stock valve sizes for the 1jz are diffrent from the 2jz?
got a reply from brian crower here it is! so they are saying it was a misprint on their site the intake valves require machine work and the exhausts dont.

You are correct with the 1JZ valve sizes. The only thing we have available are the 33.6mm intake which is +1.6mm and does require machine work to the head and the std size exhaust which does not require machine work. I apologize if the website is misleading as it will updated shortly.
Thank you,
