I'm still learning a lot on this site and I appreciate your teachings. My 261 has an 848 head on it. When I sent it to get rebored and hot tanked I was asked if I wanted to deck it. As I was unsure of the consequences I declined. The block could be smoothed out up top but what would that do for valve clearance on the head to deck surface with this head?
