I have made the decision to swap from TP to the S&S rocker boxes. I keep getting oil leaking on the rear box so I think I am going with the S&S .
Can anyone give me a list of the parts I will need with part numbers so I can shop around for a kit? Thanks in advance.

Rocker boxes 90-4110, roller rockers 900-4065A, rocker shafts 90-4036,valve springs 90-2077,or 90-2078. If I remember right 90-2077 is the steel retainer,and 90-2078 is the titanium retainer.

Keeping note of this too. My Rear cylinder is also leaking a bit... sometimes (only sometimes) I can find droplets of oil on my left Battery Cover :confused:

S&S rocker boxes can leak too. If that is the main reason for the swap you may be disappointed.

You need to pull yourrocker covers.
Pull your rockers
Look at the tops of your valve stems
Dead center clean wear mark on all stems
Your good
Off center wear marks or hour glass shaped wear marks
Bad you should seriously consider changing out to S&S Rocker boxes

George over at Papertown cycles in SPRING GROVE, PA. changed mine over to the S&S rocker boxes & had the heads redone. Man what a difference it made & how it ran.
