My EF Falcon done 200K has a leaking head gasket at number 5 Cylinder exhaust side of block.

Would the AU (MLS) gasket be the right one to fix this problem.
Does the gasket need to be sprayed with any sealer??

Also my car has been on LPG for allmost 12 Years and still run's OK would this mean the the valves would need doing, complete reco job.

I will be doing this head gasket job myself in the next week will give my feedback when job is done.

Thanks,

yeah the au gasket will work but is not the be all and end all of head gaskets,no sealer should be neeed.

as for the valves etc you won't know till the head is removed and inspected,if needed take it to a workshop and get it shaved and valves cleaned up etc.

head needs to be shaved because alloy head on cast block something has got to move with different heat values
