Cost to put new valves and springs in head?

[buck440]

I have a 06 crf450r and I would assume it is near identical to the trx450r and other motors. I want to rebuild it with new valves, kibblewhite valve spring kit.

What would be an estimate for valve guides, seats, valves, springs, retainers...ect? Mostly curious about labour.

It can be very daunting at first, but if you have enough mechanical knowledge to take a carb apart and put it back together, you could very easily rebuild the head yourself. The only special tool you would need it a valve spring compressor, I like the Tusk brand one from RMATV I bought. It did my yz450f down to my crf50.
