Use your 181 seats with the 131 valves, they will flow a lil more then the 181's alone

Also you can take the life expectancy of you engine a chop it in half, I dont care what anybody says nothing is reliable above 500 HP thats 3 times the factory HP on a 12 valve

Depends on your setup and how you drive the truck.

nothing

how much more would it flow if i used the 131 seats with the 181s? how does that work

you want the 181 seats and the 131 valves. They will flow a lil more but not to much.

131 valves have less shoulder then the 181 valves, so they will flow just a tad more in the 181 seats.
