i use to run these, very good imo
how about moving the coil pack to inlet side so leads run straight over the rocker cover
ceramic coating can be quite expensive but does work very well also
has it always been running so hot?
Thats an idea gus, will look into that.I doesnt really run that hot at all to be honest .More the fact its just the heat from the manifold and the leads are so close, its only number 3 thats a problem to be honest.
