Some cam and spring, and gasket set help needed..

What kind of build is this? Stock or performance? Talk to Oregon and see what they recommend for a spring. The stock rockers will not take much spring pressure before pushrods start punching through the rockers. It even happens on stone stock engines, because the stock rockers are already a weak link. Any type of spring upgrade and you can be in trouble. I told you this once in another thread. Are you trying to keep asking the same question until you get the answer you want? The answer is simple. You will need an upgraded rocker arm for pretty much anything over a stock spring and especially for a roller camshaft with any type of performance specs. Not to mention getting lifter preload dead on the money like it needs to be in a performance application. You cannot "half ***" convert a non adjustable valve train to a performance valve train. The reason it worked for Chrysler is because they kept lifts very low. If you plan on keeping lift in the stock range, you may as well run the stock roller camshaft. It will save you lots of money. I don't know any other language beside English, so I hope you understand.
