What were you using to control ring & pinion movement?

What do you mean? Gusseted mag case. But that did not hold..

Picture time... Easier with something to look at



Try to figure out if someone is making offset rockers for one side?

Yes, offset rockers for one or both sides would be great. But also need input on what rockers people are running. I'm not the only one running these heads. Pretty sure someone else also have had to handle this problem?

Hello, Joakim from Norway here.
 I'm having a problem getting clearance between my pushrods and pushrod
 tubes on my Competition Eliminator heads 48/40 valves. Knowing the moved
 valve guides are not doing this any easier, I wonder if you have some  
 recommendations on Rockers/rocker assembly to run with these heads to
 maybe eliminate the problem instead of machining the heads where the
 pushrod tubes are seated? The pushrods are now gently rubbing, causing a
 leak between the head and the pushrod tube (cyl 1 and 2 are the most
 tight/most issue). I have tried to shim the rockers to get as most
 clearance I can get without hitting the valve too far to the left of the
 valve center, but still not enough clearance to avoid rubbing and oil
 leaks. So do any of you have any tips, tricks or parts recommendations to easy
 my problems and put me in to the right direction to eliminate my low
 clearance, rubbing and leaks? Would love to not take the engine out of
 the car again to machine the heads. Valve/rocker geometry is as good as
 it gets.

 List of engine specs:

 CB Competition Eliminator 48/40.
 1:1.4 rockers (Think they are CB but bought second hand, so could be
 wrong).
 CB Cromo pushrods (cut to length).
 Valve-caps.
 Fast Fab pushrod tubes.
 Engle FK89 Camshaft.
 94mm bore.
 76mm CB crankshaft. (2110ccm)
 5.5 h-beam rods.
 8.7 compression ratio. (2.1mm deck height, 54CC)

 Running  hideaway turbo, watercooled Intercooler, EFI and pumpgas/E85. (Car has not been driven yet, freshly built and soon going for the dyno)

 More you need to know?

 Hope someone could help, I'm stuck trying to figure out what to do. Next
 step Is to tear down the engine and machine the heads for clearance.

(Also contacted CB for some input/suggestions)

 Thanks!
 Joakim/Norway.
