Valve guide spring seat arbor/cutting tool

[DavidLumb]

Anyone have the proper part numbers for the arbor and cutting tool to cut the valve seat/valve guide area on a 12 valve to accept the new "top-hat" style seals?

Also, looking for the part number for a similar tool for machining the rocker pedestals on a 12 valve to prep them for ARP studs?

I think comp Cams makes each of these, but having problems finding the right numbers. Thanks!

Take the measurements to see if the small block Chevy is the same.
The last pedestals I had machined cost me $60 at a machine shop,not worth buying any tools for that unless you plan on doing multiple heads

On another note the original type seals are still available

Thanks Bob. I agree it's cheaper to have my local shop do it, but anytime a tool is not much more than the cost of machining, I like to get the tool to have it for future projects. It's not the last time I'll need to do this. I have the Cummins white stripes to install with new keepers and retainers, so really would like to just do these all myself. Real machine work always goes to a good machinist for larger things like head resurface, valve and seat work etc.
