Checking valve spring heights.
Engine - 1983 318, stock heads, rotator style exhaust retainers (replaced with some used intake retainers).
Camshaft - 214/224 @.050, .444/.466 112 LSA, 108 ICL, installed at 104 ICL.
Installed height for new springs is 1.65
Measured seat to retainer height on one head. Here's our findings.
As you can see, the intakes are almost perfect.
But, because the lock grooves are lower on the valves, the exhaust installed heights are WAY lower than installed height spec.
Is this going to be a problem? Obviously the at seat spring pressure will be higher.
Haven't been able to check coil bind or retainer to guide/seal clerance.
Thoughts? Thanks. Eric and Jason.
