Fellas, I am trying to understand the difference (beyond the obvious) as to why they offer 7 degree and 10 degree valve locks. Anybody out there know?
Steve, thanks, but I am trying to understand why they are made. Is one better than the other? Is one made more for racing, or better for R.P.M.?
Yes they are more for high RPM engines. The wedge factor , or what ever you want to call it, is greater and there fore they won't come loose as easy with valve float, monster springs. . Most 10 degrees locks and retainers are made of a better quality stock than the 7's. If you are using a street type cam with the correct springs they aren't required. But if your going to buy new ones anyway ,and the deal is close go-ahead. Just make sure the retainers match the lock.
It is my understanding that the 10 degree is a better lock due to the increased surface area and the distribution of the spring pressure. In high RPM situations the are less likely to pull through the retainer but this is under severe cir***stances.
7 degree is what most engines use stock, it's the standard. 10 degree is suppose to give more clamping force, because of more surface area and are used with higher valve spring pressures. You guys beet me too it.
