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?

How many miles on the motor?
The cyl has to come off to lap them to the head If it where me, ( belive me ,I've BTDT) I'd take the cyl. off, replace the rings, hone the cyl's. inspect the pistons, lap the cyl's to the head put it together and run it. You will gain a bit of compression by removing the head gaskets BTW, what are you doing to the heads? Hell if you have tore down this far, why not rebuild it? |

Engine is out of the car while car is being painted. Bounght car with PO said was a fresh rebuild, no paper to prove it. I was resealing and going thru the pushrod tube seals when I found a few valve stems were damaged so I sent the heads for rebuild. Shop finds cracks around plug holes and yada, yada, yada... |
