Hi,

Could anyone tell me the intake and exhaust valve sizes for the RB26 head? Do people do oversize (+1mm or 2mm) on eirther when going for big power/revs (700Hp/9000rpms).?

Thanks

Syed

BUMP - does nobody know the stock valve sizes???!!

Intake is 34.5 mm

Exhaust is 30 mm.


Stock exhaust are sodium filled. They are good valves.

From what I have seen and heard, its not really necessary to change valves to you are really up there in power.
