Checking 4g63 Valve Springs

I have been saving valve springs from several cylinder heads. I decided to check the spring pressure.


I tested the valve springs using a 1.560 installed height.
For a valve spring to be good I wanted to see a minimum of 60lbs


I checked 460 valve springs or springs from 29.5 heads, both 1g and 2g, turbo and non turbo, also there is a good chance that springs from a couple of Kia/Hyundai cylinder heads made their way into the box of springs.

After checking the 460 springs only 151 springs pulled 60lbs or better, most falling into the 60-61lbs, very few pulled 63lbs
Most of the springs that tested bad fell below 55lbs, with a lowest of 32lbs.

I think what he's getting at is that if you are running stock springs you are leaving a LOT on the table.



ALL DSM's are advanced and ALL Evo's retarded

prove it, Not board, I just get a ton of questions on why I replace so many springs. So I figured this post may get the point across.

pics= proof.

Cutlass Jim, you would be spot on. I posted this one to help to answer a question in another valve spring thread.
