A quick search on the internet shows a plethora of vendors for the head gasket set and the lower engine gasket set on the 4.2 liter engine (85 SIII).

Any experiences with vendors and/or gasket manufacturers (good or bad)? It looks like the upper set can be had for around $120 and the bottom set around $45 give or take a few.....

 

"Payen" was the OEM supplier to Jaguar and I'll wager that's what most the vendors are selling. They're good gaskets. No worries.

Cheers
