Buttoning up the engine after the retro roller cam install and top-end refresh. Bought the chrome covers years ago and the 8mm Taylor Spiro Pros are close to 7 years old. Just cleaned the grease off of them and ensured there were no hard spots or burn marks. They are holding up great. Hot spark! That's a Lars-rebuilt q-jet (back around 2002 I think).... looks and performs as fresh as the day I got it back from Colorado :D
