Assuming a fresh set of late model (hydraulic cam) valve springs and other wise stock valvetrain, I've seen valve float at 7400-7500 rpms. But with peak power being made at 5200 or so, even 6000 rpms is redundant with a stock engine. The exception being the horrible 2-3 gear ratio drop, so it makes sense to hang on a bit longer in 2nd gear.
As soon as the cam profile is changed, or valve sizes are increased (heavier valves) then the rpm limits are changed for a given valve spring pressure. What cam are you going to use? Solid or hydraulic?
Today I removed my 2.2 FI intake manifold for the main purpose of substituting a spongier manifold gasket to stop a vacuum leak. I also wanted to inspect for "chroming ridges". I wasn't expecting to find what I saw.

A few years ago I replaced the front engine crankshaft seal, apparently without much luck as, I suspect, there is an amount of wear on the crankshaft. Does anyone have a recommendation as to the inside diameter of a Speedi Sleeve that might fit the bill?
