[Low-Blow]

Here are a couple of more pics. One shows the 8 new exhaust seats, and the other shows the cylinders after being cleaned up. They cleaned up at about .015. So, a question that I have is should I have them bored to .020 or to .030? In all of my ignorance, my initial thought is less is better. But, I would think that availability and cost may also be a determining factor. Also, I need to get some input on pistons, since the engine machine shop needs them. Again, I am planning on building a cruiser and not a hot rod; 4" Crank, Cam, Dual Carbs, Stock EAB Heads. I'm not looking to build an $8K engine. Any input would be appreciated.
