Cracked Valve Guide Pillars - OK to Use?

The heads would never have left my shop looking like that.
But then again....... they would be considerably more expensive than $90/head.
A lot of what machine shops charge has to do with what region they’re in.
I started in this business in 1989, and the shop I worked at had a basic valve job(disassemble, cleans heads and parts, reface valves, grind seats, reassemble) on a V8 at $100/pr.
The owner had it as a “loss leader”.
It was a huge loss.
I ended up managing that place at one point, and immediately did away with that loss leader pricing.

It’s pretty easy these days to have $1000+ tied up in reburbishing a set of 40-50 year old iron heads.

And that’s before the porting happens.


Any machine shop using loss leaders to drive business usually don't last long.

The other thing that happens when you price like that, you get the tire kicking coupon clippers who look to cut corners, and when you do, it ends up on the internet making your work look bad.
