Got ripped off. Looking for a new idea for the inside of the engine. Stroker maybe?

A.O.C, Charrlie will guide you down the right path.I hold him in very high regard on slants. As stated you may have to bore to clean up the cylinders.That case it means new pistons and the cost for .020-.060 pistons will be about the same.Now if you ever saw a stock slant piston, they look like beer cans. Aftermarket pistons to me are much better.It sounds like you have the head done already and shaved .100. If that is the case only take as much as needed to clean up the block and get it straight.Last but not least find a shop that is trustworthy.Again Charrlie sure knows who to trust in your area.
