[Land-speed] Copper head gaskets

[drmayf]

Hey, Neil, can you use a set of them from my sunbeam motor? I used them 
up to 18 pis boost and they started to leak between cylinders... torque 
was 110 on long  head studs and 100 on short ones... So far no leaks on 
the SCE ICS Titans which ar eon their first reuse...
