Re-use head bolts?

[Anonymous]

Hi guys,
Puting a rebuilt head on a 170. I had the new head on for 1 month & found some issues that I made the machine shop redo. Used the old ones last time. 135k on original head bolts. Do I re-use them or get new ones? They look great. I dunno?
Thanks,

If they look allright (threads, etc) I would reuse them. I've swapped heads 8...10...12?? times in the past few years with no problem.

If you mill more than .040 or .050 off the head or block, I would use some hardened washers under the bolts so they dont bottom out. The Mr Gasket part number for the washers are on my website somewhere...

Later,

Doug
