Reply to "engine cam bearing oil restrictor install,yes or no"

I hope you don't think badly of me for opening this discussion but I think its a very important topic to cover before a rebuild. And George forgive me for doubting your recommendations. Like most people I got advice from a lot of different sources including engine rebuilders, all saying they are correct. In the end its all just words you put your own money behind without prove their advice works.
My story is, I had my engine rebuilt by a shop specializing in racing engines. Willing to spend some extra money to get good work, its only now years after the rebuild (I parted out the car and engine has been in storage for a number of years) that I find the mistakes. Cylinders not bored correctly, block decked too much and not perpendicular to the cylinder bores, front cam bearing set to far in, did not replace stock 4v valves as requested and did not install cam bearing restrictors as requested. I also had a set of Australian 302 heads rebuilt and now find they machined the pedestals too low( too much material removed). When I disassembled the engine, the crank and connecting rod bearings were worn to copper and this was a low mileage engine after the first rebuild!,and the cam bearings were worn and chipping away also.
Now fixing all the problems with the help of a local man specializing in Cleveland's, I found he installed the front cam bearing not as per the ford spec's(too far in) exposing more of the oil passage but he said to leave it that way. This man has been racing Cleveland's for years with his own modifications without bearing problems. But not wanting the same problems again I'm questioning everything now.
So posting the question, I hoped to get the evidence I was looking for to make a sound decision. George just to add, your sticky on Cleveland's is the best info I have come across, thanks for posting.
Thanks for posting the reply's guys, I decided to go with the restrictors so the short block is coming apart again and the restrictors are going in.
