I had a heater hose blow off of my 85' 626 and I warped the head.
I swapped it with the head from my parts car.
I reused the original head gasket and head bolts. 😂
I just sprayed both sides of the gasket with copper silicone spray gasket.

NEVER let your oil go below the low mark or you...
That happened to another guy.
He just sprayed down the linkage with lube and got it going again.
