I'm looking at a few websites to order an engine gasket set (need head gasket, valve cover, valve stem seals, intake & exhaust, etc), specifically fjparts.com and sor.com, and want to make certain I'm getting the right set and the best value. My 1969 FJ40 has the F145 (single-barrel) engine, so am I correct to order the 1968-9/73 set? Any suggestions for other sources, whose is best or who to stay away from?
