Do you do a lot of towing?
No offense intended, but personally, I don’t care for the tow mirror look.
Lol no I don’t. Well not anymore. I only bought these for a camping trip from Texas to Yellowstone starting next week. Since we are renting the trailer I wanted to make sure I could see everything I needed to. When we get back I’ll be swapping back to the normal mirrors.

Bead blasted carbon off of the valves.
Debating if i want to polish them before i seat or leave them as they are.

Thanks to the shortage and outrageous prices here in California for catalytic converters, I decided to do the entire exhaust. Luckily my smog guy does not look underneath and with 250K miles I wasn’t about to drop almost $4k to replace both sides. Found a company in Canada that doesn’t care about CA emissions regs and shipped me 2 brands new ones for $300 shipping included. Went with a Spintech muffler and dual tip out. Will post sound clip when I can. Best setup I’ve had yet

Did some valve polishing last night.
Started with medium crossbuffs, then fine.
then broke out the wool/felt bits with polishing compound (harborfrieght).
Next i break out the air Dremel since i have much better polishing bits for that.

doing some high polish on the valve faces and stem part where it does'nt ride in the guide.
Ran the valve through the ultrasonic cleaner afterwards and i started noticing something.
on some of the valves, there is a clear gap between the stem and the tip.
like i can hook my fingernail under it.
Makes sense that they would have a hardened tip, but is this normal?
fresh cleaner still on this one, but notice the line.
One of the valves i noticed it's almost not straight...
