Xtreme Duty Valve Springs - Most 1.550" Single Springs up to .525 valve lift on hydraulic camshafts

Valve springs are one of the most critical and most overlooked components in your engine They must be matched to your cam in order for the engine to reach its full potential It does absolutely no good to install a cam that will RPM at 8000, if you do not have the correct springs The use of the wrong valve springs is one of the most common causes of engine failure Another is the incorrect installation of the valve springs.

Note:Specify exact cam specs when ordering to verify compatibility.

Inconel Exhaust Valves

These valves have become the standard upon which all marine heads are constructed. If someone is telling you they have a valve just as good or better than a Manley Inconel valve "Beware". There's a reason they are the choice of real marine engine builders and cylinder head manufacturers, no other valve has the ability to make the claim of having over 1,000 times the fatigue strength of other competitive valves.

Note: This one part in your engine quite possibly takes the most strain of any given part in your engine.
