Jeez... this post has got me questioning my memory on what parts I bought for my future 451 build: Did I buy a new Pro-Gear standard set with a spare -.005" chain, or a -.005" set with an extra standard chain?

I figured since the block had been align-bored for aluminum caps that I might need to run a shorter chain (like I do w/ my 452 block), but was hoping to have both bases covered when trial-fitting everything.
