Product Description

By entering your model number, you can make sure that this fits.

For one cylinder, a set of two springs is sufficient.

Measurement of piston-to-valve clearance, rocker ratio, cam degreeing, and other parameters can be made easier.

Valve springs can be replaced with low tension checking springs, which can be done by hand.

4758-2 is the part number for this item.

Questions & Answers

Will these fit in a Ford flathead?

I believe they will work as long as you can access the engine's springs, and I am confident they will work on any ohv engine.

Selected User Reviews For COMP Cams 4758-2 Checking Springs

I had to cut off a couple coils for the wide guide boss base, but it works

4/5

I had to cut off a couple coils because they don't fit through the wide guide boss bases on Vortec heads and end up on the shoulder. I had to cut off the bottom couple of coils in order to get full valve movement. They were effective once they were completed. These would work well for bosses that have a smaller ID than the springs. br>It's used to check the retainer for clearance and to degree the cam.

Issues with the design: the springs are WAY stiffer than they need to be

3/5

To keep the spring from compressing my hydraulic lifters, I had to cut about a third of it off. Would work fine for checking pushrod length, but would need to be modified if you wanted to check piston clearance or do anything else with the valves off the seat.
