Converted,I send a e-mail about 2 months ago concerning the valve springs in the cam kit for a voodoo 60303.

Because of oil-leak my engine is apart. I tested the valve spring in a tester because the camcard say installation height is 1,820"? 120lbs.

Have 4pc 906 heads and they all have a installation height of 1,950".

They tested at 1,950" 75 lbs thats a long way from 120 lbs. Thats way I contacted Lunati tech. and still waiting for an answer, why they sell chevy valvesprings to a mop BB engine.

So thats why I try Moparts.com instead.

Don't buy the cam kit, I'm happy with the camshaft ,but NOT with the lifters and valvesprings.
