Stock Rb26 Head Capabilities?

[Nesquick]

how much hp can a stock R33 head handle?

im looking to get my car runnin this summer with just my stock turbos.

but next summer im planning on swapping to a gt35r and maxing it out. (~650hp)

will the stock head be able to support this kinda power or will it need to be upgraded?

if upgrading need be, what would be needed?

RB26 head is good to go.

the factory gtr head is stout w solid lifters n filled valves... good head that flows well even in stock forum

The head casting itself is easily capable of flowing that in unported form. Your cams are going to be a bottle neck at that level, but you could still make 650hp with them. You'll just need to run more boost to do it.
