I spotted this some months back working at an AC Delco distributor...
AC Delco 45K0187 - They say SPC right on them. And they're cheaper. By a lot.
They're exactly the same ones, I have em. SPC camber arms even with SPC cast into them, $40 cheaper a set
It's official - I've had the car five years today and accumulated a whopping 32,818 miles. Just think: sometime around 2023, it'll have almost 100K!
Head surfaced today. It was 0.006" off. I've heard from John at PTP that he saw a head recently that was 0.017" off. That's a LOT. Apparently these things are pretty loosely cast from factory. But in good news, they ran vacuum and everything they could see was my valve job is very good and there are no valve stem leaks.
96k on the stock head, and I did mild porting 15k miles ago, everything's still good! Saved $200 on a valve job!
I think he said his commute is 6 miles a day, which is also shared with other vehicles
.017"?? That would never seal... especially with a MLS head gasket. Sounds like a overheat and warped head... which would probably need a straighten and stress relieve to make sure the cam journals were straight and no load on the cams. Before my current job, I worked at an engine shop and cylinder heads were my specialty. When my motor goes, the head off my block is getting the works on the Serdi
This is the shop I used to work at.

WHOA!!! Not good mileage for the car. Barely enough time to get everything up to temperature in 6 miles.
I used to own a Colt Vista (Mitsubishi Expo by another name) which was a pretty good car, all in all. But when I got it, I only lived 1.9 miles from work. Unfortunately, it was all uphill, and I work VERY early in the morning, so walking/biking were not good options.
The car never really warmed up and my mileage was around 15-15.5 w/a 5-sp manual. We moved to nearly 20 miles away sometime later and my mileage jumped to well over 24 mpg!! By then though all those short miles had taken there toll and the car was failing. Burning oil, clogged O2 sensors, etc....
I don't feel so bad about his mileage vs mine then. My commute is 17.25 miles one way, but I have a lot of vacation with my job too.
