Need intake valve

[vorsberg]

I just found out that I need an intake valve.
It is larger than stock , 1,771" or 45 mm with 0,3407 stem dia. and 4,713 OAL
Google was not my friend this time....
Anyone who knows where to buy one ?

Manley or Ferrea is the best source for the bigger intake valve. The Ferrea number is F6238. A Manley 11504-1 is available from Summit. If you need a whole set change the 1 to a 6. I have used both brands. The head of the valve is 1.775.
