So, I've been reading here that head gaskets are a thing of the past, I guess lapping is in. That said...I pulled the heads off a few weeks ago and sent them out for a rebuild. It had head gaskets on it.
Whats the process for lapping cylinders to heads? Do I pull the cylinders/pistons off the rods as a whole to preserve the rings? Toss the rings and rering too? I did a compression test recently with good results, 135-140-140-138. I was just going to replace pushrod tube seals...this is getting out of hand. What would you do?

By removing the head gaskets you will be changing your compression ratio.
Just keep that in mind. It also changes your valve geometry. Why not just get a new set of head gaskets and put the heads back in place??? Rich |

I know my limitations and screwing with the valve geometry goes far beyond what I comfortable with. Is there any tricks while using the head gaskets to help eliminate the possibility of a leak? |
