Valve Lash using Vmax Cams

[GaryZ]

Ok gang, I have a question and this is the place to get lots of opinions!

 

I have installed Vmax cams and springs in my 1987 Venture 1300 engine. Venture intake valve lash is the same as the Vmax. However, exhaust valve lash is different;

 

Venture: .16 - .20 mm

Vmax: .26 - .30 mm

 

Which lash will be right for my Frankenstein?

Vmax Clearance is the Way to go.

 

The Vmax Valves are different smaller Stem and therefore expand a little more when the Engine's running.

Squeeze,

 

GaryZ's doesn't have the full heads, just cams & springs.

 

Rest of head is Venture with stock valves.

 

Still go with wider clearances?

Oh, I'm sorry, my bad ...

 

For Venture Valves, please use Venture Clearances

Alrighty then,

 

Shim tool & valve shims are on the way to me. (Thanks MiCarl)

 

Glad I found out about this now before all the plastic was back on.

 

Vmax service manual shows same as Venture in one place,and different in two others.

 

Guess which one I read.
