Once heads are o-ringed that's it right? Have to have bolcked ringed also correct? Never seen a set so i don't know how deep they groove them. Seen a set for decent price but are ringed.
If the Heads are O-Ringed. You do not need to O-Ring the Block. That can cause some kind of levitation. If you are uncertain with just the
Heads. What people do like on my Stage Motor their is a Groove on the Deck per Cylinder.
