I ment would the proper (bigger) seat for a 1.60 valve work better, as in flow better, than trying to max it out and make it work with the stock seat. I have already swaped out the 1.60's for 1.57's. Ill be shipping them of to TEA in the next week. So they will be 2.055/1.57.

Shouldn't need a new seat unless the valve has been sunk a lot from previous valvejobs. I don't see how it would be beneficial to replace the seat otherwise.

2.02/1.60 is what I run, it's pretty close to the limits of stock seats.
