valve springs

hi guys what valve springs are you using in your race motors over there. I am running a 3.1 in my 240z and am in the process of assembling a new head for next season and would be interested to know what the general concensus is on this subject. The springs that I am running at the moment are a set from the late David Weber, but that was 3 year old info. Cheers in advance for your replies ben

I put schneider springs and retainers on mine. I think MSA sells the spring and retainer package for about $100.

Anyone correct me if I'm wrong, but I get the feeling that Schneider sells the same set of springs for all of their cams. So in other words, if one is running a milder cam, the spring tension is probably more than is needed, but it's not hurting anything other than creating more friction than nessesary. Just my .02 cents.

thanks for that, do you know what the spring pressures are both closed and fully open valves. the set that i got from malvern were 125lb closed and 260lb open. Are the retainers that come with the set steel, and are they different to the origonals. many thanks ben

I don't know the spring pressures. I didn't check them for that, just for binding with my .572 lift cam and installed height. Schneider shows the same part number on the springs for all their Z cam grinds. They have a few different retainers, depending on how thick your lash pads are.

Their valve springs worked to solve the valve float problem I was having with the stock springs, and thats what I was looking for. I used reground rocker arms with a new cam from them and ended up with some problems with wavey wear patterns on the intake and exhaust lobes and rockers on 1 cylinder pretty quickly. I'm not sure what caused that though as the other 10 are still perfect ......
