I put the spacers in when I installed a 600 cam. I pulled the jugs to cut the bases to get the compression to 12.2 so the heads were off. That effectily made my pushrods .060 longer and I did not use lash caps. I know you are saying they are adjustable push rods so what is the worry. When I did my first prototype I made it .200 thick and with travel limiters in lifters the there was not a lot of thread engagement on the adjustable push rods. The .100 worked better for the geometry anyway.

You ran 12.2:1 compression with the S&S .600 cam ? What gas are you using ?
If you raised the rocker box .100", what thickness lash cap were you thinking of using ?

My bad on the compression ratio. It is 10.2 to one. I did this 01/27/10 and I got my motors mixed up. The 12.2 was the car in my avitar and I ran it on racing fuel then converted it to run on E85. I have never used a lash cap but when I was running out of push rod threads I was thinking of something like a .080 cap. When I went to the .100 spacer instead of the .200 it was ok. Did the E85 thing ever happen in the street bike world?

Good, glad you figured it out.
If you had used a .080" lash cap, that would have been the same (geometry wise) as reducing the thickness of your spacer by .080".
I don't know of any bike builders messing with E85 .

Another 1 bites the dust. You can lead a horse to water, but you can't make him drink.
You can't fool geometry. If you don't think you have a problem, sooner or later you'll get bit in the ass with TP rocker boxes on S&S heads/engines. I've had owners tell me their bike is running great, and when I take it apart for the mods they want, I discover valve train problems. Here's the latest 1 to come in. I think the owner said it had 50,000 miles on it.

Are these my heads John?

The misalignment is caused because the valve stem protrusion in the S&S heads is far greater than the protrusion that the TP rocker boxes are set up for.
The TP rocker arm shafts will work with the S&S rocker arms. I wouldn't gamble with the TP rocker arms. If you're using cams under .600" lift, by all means use non-roller S&S rocker arms. :eek:

Im still stock all the way through. What is the OEM cam on an 05 Ridgeback pls?

When you say stock, does that mean you still have a restrictor plate behind the carb? Is it an E or G carb? Do you know if you have the EPA smaller valves? If you have G-carb and bigger valves you can use the 600 cam which has way more of everything. If smaller valves or E Carb then 585 is the way to go. Curtis has the 585 that just came out of my 2005 Chopper when I upped to the 600. He will make you a good deal on it. Changing nothing else but the cam from 585 to 600 was the most dramatic change I have made. But it took all the previous mods to enable it.
