Thanks Kim
I have the 'mushroom' tool for removing the guides but not the special guide to assist with valve grinding. To be honest, I am hoping not to have to go so far as removing pistons but that will depend on what I find once (if...?) the head comes off. The present cold weather does not exactly encourage 'garage activity' and the car is useable and MoTd, so it may be a while yet before I start this work. I admit to being strictly a fair-weather mechanic but have plently of other 'kitchen table' jobs to be getting on with. Like sorting out why the wiper only goes one way and stops when the knob is pulled out, and then back to the park position when the knob is pushed in again. This is fun to demonstrate to first time passengers (if they have plucked up the courage to open their eyes) but definitely loses its novelty appeal in heavy rain !!

Maybe you've just got too used to the phenomenal power of the Pop!  
I had simular problems, lack of power and on hard acceleration, pinking !
I thought obviously the timing needed adjusting but no matter where adjusted, couldn't get it to run as good as before.
I ended up giving the engine a de-coke and has been great ever since!
Hope this helps,

That was obviously not pinking. It was detonation.
They sound very much alike but they are rather different.
Pinking is caused by a early ignition causing pressure of combustion to rise excessively before the piston reaches tdc. Can cause damage to the big end bearings as well as lost power.
Detonation is generally caused by glowing carbon deposits causing the mixture to explode before the timed event rather than burning normally. Can cause damage to big ends, but is equally likely to blow holes in the piston crown.
