Yes this is normal. I used ARP hardened washers when I assemble strokers. It clears perfect. You also need to clay your oil pickup to make sure you have the proper clearance from the bottom of the oil pan.

I had the same thing with my 383. I about **** when I turned the engine over and it stopped. Fortunately it was still on the engine stand. Wish the builders would pass along that info. As well as......the newer blocks use all short head bolts. 
Found that one out too.

I noticed when I was fiddling with the pulleys and belts that there was a scraping noise when I turned the crank over. I listened real carefully and thought it was just the new rings scraping on the freshly honed cylinders. I did notice that it had several catches per revolution. Then I decided to put a new oil pan on because of twisted off bolt on oil temp sensor and woops I dropped a bolt beside the oil deflector and it went tink tink tink deep into the motor. I tried a magnet first and then flipped over the motor and shook it to no avail. Off came the intake and valley cover-no bolt so I flipped it over and the bolt came out. When putting the deflector pan back on I noticed some metal shavings on 4 of the rod bolts and was confused until I looked at the inside of the deflector and saw the scrape marks. I beat the pan out a little where the marks were and put washers under the pan before bolting it up. I have good clearance on the pickup so now I am good to go.
I was really mad when the bolt dropped into the motor but as it turned out I think it was some higher power doing it to get me to see the problem. Maybe it was Bill W. 11+years now. Most of you might not get this.

i had to shim my defelector and i clayed the pickup tube as well......next just as important thing to check it the front connecting rod bolt to oil pan. my #1 rod bolt hit the pan as i luckally was turning it over on the stand. i about **** . i turned it one way then the next it made two little dimples in the pan. i took it and ground it out clayed it and had over .060 clearance so i called it good.
