Again, what does your camshaft have to do with anything? No one cares what you have for a camshaft.

Congratulations you found an ovate spring that matches your cam that doesn't require machining. That is not the case with every cam/head combo.

How does that help the original poster when they don't make an ovate spring strong enough that doesn't require machining the spring seats? The spring that you suggested is for a hydraulic roller which the original poster DOES NOT HAVE.

Note: solid roller cams have steeper ramps than hydraulic roller cams(generally) I would also be concerned that the heads have screw in studs

I don't have a camshaft and do you have ovate springs that need machining? Is the camshaft you refer to the Reed cam Bobby wanted spec's to in 2009?

take Enginezar' s advice .
The comp dual springs are not hard to install
your engine shop will probabily have the seat cutter

solid roller cams need specific springs

comp cams will advise call them

If/ setting the valve lash cold --- set it -.004 to-.006 tighter than the hot lash spec
