should i go .20 over bore or stock bore?

[deviousgst]

im in the middle of rebuilding my motor again due to denation. My question is what should i do, should i stay standard bore or should i go .20 over. My cylinder walls are still good on the stock bored. Im going to be boosting 25+psi and hopefully around high 300hp..
thanks in advance

It really doesn't matter then. You won't run into any issues with running 20 over. Your regular HG, steel or felt, will work, and it doesn't really improve any performance. I did 20 over just as a convenience, plus i had a little scratches in my wall, so 20 over cleared it all up, and it worked out well.
