I have a '74 and noted that many have recommended larger exhaust valves. BPN 
sells 32.5 mm (1.28 ") 21 4N SS valves, which is substantially larger than 
my stock 1.195" valve diameter.

Do I just ask the machine shop to grind a larger seat?

Also, do listers recommend the bronze valve guides?

Thanks
