Quick intro - I'm based in the UK and have has my '79 SE for a dozen years or more. It has been in the shed for the past five but I have finally got round to rebuilding it. I have been offloading some other projects to fund an ambitious project...
277 rephase, 750 big bore kit (both Heiden Tuning), Pamco ign, PMA conversion using VF500 stator and reg/rec plus RD350 rotor all spliced with a Rick page adapter plate, fzr600r monoshock, s/a, rear wheel, matching fzr front end (all sitting in the garage waiting patiently).
So, to the issue at hand - I have broken the engine down ready to ship parts to Heiden and have been checking over the cylinder head. There is a tiny bit of play in each of the exhaust valves (between valve stem and valve guide with springs removed). I have a spare head from an old spare engine which has no play in any of the valves, but the head is in overall worse condition (could be salvagable...).
If I bake each head to remove the exhaust valve guides, swap them over so I get the good ones in the good head, will they still need reaming? Will I have to recut valve seats to match (I'll be lapping valves anyway)? Should i use the valves (cleaned up) from the spare head too?
Any thoughts would be most welcome
