Is there enough meat in the eagle head valve seat to install 6.4 valves or will it cause a problem with the seats?

you can do a 2.14 intake but not both 2.14 and 1.645.
I'll do 2.10 on the oem seat but 2.125-2.165 I change the seat, realistically 2.14-2.165 there's not enough room under the seat to get the throat to with in 90% of the valve size.
on the exhaust side 1.625 is about as large as you can go,
I've done 2.125/1.625 and 2.14/1.60. on Face book I saw some do 2.165/1.625 , not me , I think that's a seat drop waiting to happen.
