What valvesprings for the F11? After searching I'm pretty much sure this is the one for me, just curious if 918's will cut it or are there any other singles that can handle the lift? If not, which double springs would be best? Thanks.

IMO it's always better to go with a double spring but one of my buddy's is running the same cam and he has 918's with no problem what so ever so I am pretty sure you will be ok with those.

My friend has been using 918s with the F11. He had been using them before with his Hotcam. After the swap and a few thousand miles he dynoed. It looked like there was some valvefloat. Not sure if it was the new cam weakening the springs, or just time for them to go.
