Has anyone here built a 914 Type 4 using the LN Engineering 2563-190 kit?

QUOTE(zig-n-zag @ Dec 27 2024, 05:39 PM) *

The camshaft in the engine kit is the 163/86b. What makes this cam

different is the 104* lobe centers. The dual valve springs will need to be

cryogenic treated so they can maintain proper tension to the valves and

hold the lifters to the cam. If not, the valve hits the seat a little off,

Damaging its ability to seal, there by losing power. Left to continue, it will

Wear on the valve guide and valve stem, and eventually having the valve

Heads touching each other while opening and closing. A clue to having the

Valve springs lose tension is an increase in valve lash. This is critical if you

Want to run real big valves like 48 intake and 38 exhaust.


Not sure I understand some of this...

"Valve heads hitting" and "gaining lash from weak springs".
