Get a new machinist. He told you it was an L26. Then he told you to get standard L28 pistons. Obviously he didn't even take a measurement or know what the bore size should be. He should have given you a bore size number to work with. Even better, he should have ordered the parts himself. He's wasting your time and money and will probably do a poor job.

You could have bought a good running engine for less than $500.

I agree with the statement above!
Your machinist is bad, the size of the pistons is usually stamped on them, he did not even look at them carefully.

I had good luck with www.clarksdiscount.com, Carl (the owner?) was awesome with me & he has everything for your engine (see where I live!)

I would first of all work on your spelling - you will get some faster and better responses from this site.
Second of all I would get a new shop - if this guy has screwed this up from the beginning it will be a train-wreck once he finishes the rebuild

Call Dave Rebello (http://www.rebelloracing.com/)- he can send you all the parts and pieces that you need or just send him your block and head and he and his team will perform a little "Rebello Racing Magic" to it.

Life's a journey; enjoy the ride!
