I can't afford the big bucks to send this out to a shop. I was hoping I could get away with not having to machine the heads.
Has anyone ever done it this way?
You're not going to be able to change your seats at home in your garage, but the guides are doable if you're handy, reasonably experienced, properly equipped and careful.
I don't know you, but it's probably not the sort of thing you want to try alone without a bit of guidance and the correct tooling. You could do a lot of damage if you weren't careful.
If money's tight, take the heads to a competent auto engine overhauling shop with CC Products guides and new exhaust valves in hand and specify 1.5mm valve seating surfaces. (iirc?)
Better double check that spec.
edit: or wait until you can afford to send them to a motorcycle head specialist like Randy Long.
