another overheating problem

Yahoo I talked to home about boring the motor for me to get it right not for performance and he said 150. Not bad at all imo. Since I'll have to get it bored later should I have him shave the head down a bit. I don't want to go the whole .100 but I don't want to lose compression and make the motor have less power. Maybe .050? I'm let me know and I'll give him a call in the am lol. He said it won't be ready til friday
