Henry,
I didn't really think much about removing material from the bottom of the rod caps - appeared this is where material is removed from most rods. Meanwhile, I have no doubt where you indicate is clearly better from a structural standpoint.
I was however somewhat surprised by the crude grinding appearance on the rods. My reference was this video that I found on rod balancing (great vid if you want to know how its done).
Connecting Rod Balancing - YouTube
The guy uses a belt sander and makes a smooth pass to remove material, which would produce a smooth finish as Henry suggests. Meanwhile, looks like my guy hit it with a bench grinder...
In spite of this, I think the machinist I used is good to go. He has pretty solid knowledge & experience with old VW engines - I guess he's just not sophisticated enough for the Porsche community
.
When I picked them up, I really did feel like asking him "can you make the grind look purdy?
Thanks for the info Henri - good stuff to know before you go marching off to a machinist.
