Who has used Chet Herbet Valvesprings ?
Are they American made ?
Thier Facebook page says they are.
Down to the wire on valvesprings for my 65 Olds 425.
Have all to rebuild & New Isky Cam.
I can machine the spring pockets deeper up to .090" inches Min.
1.430 OD.
1.750 " installed heights.
Likely get 1.812 " if I used offset retainters and offset valvelocks.
The only Drop in Valvesprings I have found are Comps 901-16.
Have to shim .020"to get 1.670" factory heights. Kinda of a weak valvespring and singles.
Herbert has a package deal on Nice appearing duals & Titanium valvespring retainers.
Can always get Isky.
