Problems and upgrades questions

Hi everybody,

My chim 500 jerks under 2000 rpm, I think replace the angled spark plug shroud for ceramic wires like that :

But it's not avalaible, I find alternatives like accel 9002 but in black and I want blue wire, Taylor set 85653 is it ok for chimaera ?

Alternative idea for ceramic spark plug with blue wires please ?

I also think about put new eprom chip but I don't found 500 firmware here :

What firmware choice for chimaera 500 1999 ? It is the same for 450 ?

Last question, my car hasn't running during long time (6 months), I thing I have Hydraulic Valve Lifter noise, is it necessary to replace all the hydraulic Valves Lifter ? Or the valves will initiate with the oil during a long run ? My car have only 35 000 miles on clock.

Thanks from France
