I scheduled a 98" FM build with TW-555-6R cams in 4 weeks. Should keep me entertained for a bit. Had the compensator nut back out at 12K miles so I feel with my luck the cam chain tensioner's should fail soon. Now with the motor build including the tensioner's I shouldn't worry about that anymore as long as I can make it to the build date.

Anything else to address?

 

I'll be following the build. I am getting ready to call FM and order the same. Trying to decide if I should go with the TW-555 cam or not. I have an 02, so I would need to upgrade the valve springs. I think a buddy has a set of SE prings that can take the lift. I can't spring for the B heads right now. Good luck and enjoy!!

Any Dyno numbers if heads are added to 98" kit? Are we looking at a wider Tq curve?

 

If you find the thread started by Jamie when he announced the 98 kit you will see a whole progression of the tests he performed during development of the kit. The heads make a big difference.
