I am running haisleys STD 4.560 d .105 wire head gasket. I recently pulled the head due to an overheating issue. The firerings them selves are in good shape and not cracked. My question is what crush is needed to keep them sealed? I am running A1 studs and they were TQ'd to 135 with several TQ's after.
I blew out the gasket on 2,3 and 5
Thanks alot for your time
 
All comes back to machine work.
Poor quality machine work can be masked but never lasts.

as of now the block has never left the truck so you think i will continue to blow gaskets till i get the block decked? The head was straight when i put it on, i have never checked the deck because it was never coming out.
 
He must be pretty good with a straight edge to be able to check a block down to with in a .001

Yea I just used the shops straight edge and a feeler gauge. How true it is I don't know. ( For the moment I cant have the truck down. i am building a seperate engine for a spare soon) I never got a chance to check the crush. I will tonight and report back.
