R500D head gasket replacement

[Waitey]

Hi All,

Can anyone suggest a good place to take my R500D for a head gasket replacement?

Thanks

Already at 305!

He wants it out of the chassis though and that’s a bit of a bind as I need it for an event soon.

To answe some of the questions;

Not sure why it went, it just started pressurising the coolant heavily. Head lift at 9000rpm could be a possibility, it has ARP head studs though, so you’d assume it wasn’t that!

It has an arrow keywayed crank, so the crank timing is pretty much set.

Cam timing would be a worry.

It’s already on Omex so map changes aren’t the end of the world.

Yeah new expansion tank and cap which have been tested.
