If you find the bead blasting of the journals to be an issue when you go to fit the camshafts, let me know. I have a spare 1980 '850 head sitting around doing nothing that you can have for the cost of USPS shipping.

Took head and barrels to get bead blasted. The guy said no worries will not glass bead around cam area, sure enough glass beaded everything. I have used 1200 grit paper and smoothed out cam bearing holders and valve cup guides. Lots and lots of fine glass bead everwhere. I have washed the parts down 3 times with soapy water, pressure cleaner and then compressed air. Hopefully I have got it clean, will find out when its put back together, will be a very nervous time.
