I would call Dan at "performance only" he searched high and low to find me a set of the pistons I wanted, I was looking for some .020 over 340 pistons for a 4 inch stroke and aparently they are hard to get, no one else could get me what I wanted but he did. If he don't have it in stock he will find it for you.
I know a ton of the other guys on here recomend him also and out of all the bad talk about people you read of on the internet I have never heard anything bad about him.
