On a stock V twin (SE stage 1 upgrade)is one really better than the other. The standard gasket looks like it would seal better to me and the SE cost more. I would like to get it right the first time around, the extra cost doesn't matter.

 

as long as they're installed correctly either one will work. i used se cause that's all they had in stock.

 

+1, I used the SE just because it was available

 

Supposedly the SE is easier to get seated in the port. I always use the stock gaskets and they work great. Less $ too.

 

+1.....the stock ones are a PITA to get in, but they look like they'd seal better

 

Stock

 

+1 on the se gaskets. steve

 

SE just so you can give harley more money and tell everyone you upgraded to SE

 

the stock ones seal better. I have seen a few instances where the se has allowed the pipe to loosen up and ruin the port in the head
