head gasket 1300 05
guys i know this is a big no go normaly but for a few runs could i get away with running a head gasket thats been used..
although it was torqued down and used for one session it still looks good on the compression edges...
only want three runs out with new heads to get rpm readings to get prop pitched...
would use new but on waiting list for head gasket for two weeks and even if i order in states time customs get it and postage will be same time..

If I was you (meaning in a bind) and I was running aftermarket 3 piece heads I would do it, but keep a close eye on it. I would NEVER think of doing it with the stock 1 piece head. Everybodys opinion will be different, this is my .02

on a whim, i have installed a used stock gasket with one layer taken off on one of my ski's . compression/leakdown test excellent. have over 20 hours on it without a glitch. but, i intend to replace it with new as soon as i get the time. its worked for me, but not sure if i would recommend it

Make sure it is clean and no debris is between the layers. Apply a thin film of waterproof grease to the sealing surfaces and reuse it. I have been. Just look it over and make sure the sealant is intact and it is clean. Cleanliness is paramount.

I have re-used head gaskets with no problems at all using this method.
A-Clean thoroughly then very lightly scratch both sides with #400grit
B-Using spraycan coppercoat spray both sides with 1-medium coat
C-Allow 20 mins. drying time for proper texture
D-Install onto clean cyls & head and torque to specs.
25 Hrs on my Wifes ski-no problems
May not be a good Idea on big bores past 86mm
Thats my 2cents and there copper
