Black valves and other information
There seems to be a bit out there on the interweb talking about black nitride coatings for valves - don't think an M102 has this though!
SuperTech Black Nitride Coated Exhaust Racing Valve-1GRFE It is probably just more ming. Here's a bit of information about valve condition which is quite a nice read Exhaust Valve Leakage - a photo essey

If the motor is staying NA I would just make sure they're not warped and check the seats with machinist's blue.
Look up the packaging/ shipping requirements for international HAZMATs and I'll ship you a case of it. It's flammable, corrosive, and dangerous for skin/eye/lung contact. But it melts the paint away while you watch. A roll of paper towels and a half can had my motorcycle's tank down to bare metal.

Yep there's no stopping those valves from hitting pistons - this thread is proof of that!

Fitting the pistons!
After measuring the weights of the connecting rods, wrist pins, rings and pistons see above I managed to get the heavier piston set to be a little bit closer to the others. In the end the piston sets are within 4 grams of each other.
![]() Not exactly what I was aiming for but I didn't want to remove any more metal from the underside of the piston or the sides of the conrod - I chickened out ############### I'm using this assembly lube Maintenance & Preparation | Assembly Lubricant | ASSEMBLY LUBRICANT As it is pretty gunky stuff I haven't splashed it about like you might with normal engine oil. The rings got lubed prior to fitting. Making sure the gaps in the rings are equi-distant ![]() Fitting the piston in the ring compressor ![]() Pushing the piston into the cylinder - make sure the conrod doesn't smack into the crank journal ![]() ye olde hammer handle... ![]() Make sure they're in the right way! ![]()

If Im not mistaken the oil scraper ring gaps are on the thrust side of the piston, I was always taught that you arrange the gaps as such that no gaps should be on the thrust side of the piston.

...tortuous route etc... Piston ring - Wikipedia, the free encyclopedia I can see why you'd want to do that trick you mention though it could help by not digging the ends of a piston ring into the cylinder wall on the power stroke if they happen to be a bit sharp on the corners. In the long run, however, it is possible that the rings will rotate - they won't necessarily stay in the same position as they were fitted.
