[Roadsters] R16 - How to get .425" Valve lift?

[Daryl Smith]

No answers to the last question so let me put it another way......

How do I get .425" Valve lift on an aluminum R16 head.
I had a cam with .387" lift which crushed the seals (exhaust only) and wanted
to increase the lift if I could without too much difficulty.


Anyone have any tips on whats involved? Any way to do it without custom made
parts?

Any advice appreciated!!
