With all due respect
My limited engine bolting experience have found Right Stuff is awesome seals great is expensive, Ultra works great does the same job is lower cost.
The difference is Right Stuff cures quickly when you need to get the engine running now, Ultra takes a while to cure you have to have some time to let it set up.

Both are great products.


If the china wall or back of intake have been milled for port alignment you will need to apply a high amount of either product to seal. Make sure the distributor opening is clear when it squishes a finger swipe may be required.
