Which head gaskets do you use when putting 241 casting heads on a 6L?

 

Use the 6 liter MLS gaskets.

 

Oh My God !!!...someone else is gonna do that swap too ...I think it's probably the best way to bump the compresion up and still have a great-flowing head

When I did mine I used the Felpro 1041's......they seem to work very well !!!!

 

The FelPro's are good. The Cometics are better. Down side is both are pretty expensive.

 

You will need to open up the chambers for the increased bore size, or you will get shrouding which will hurt the flow. Ask me how I know....
