I am having a problem with not getting enough oil to the rocker shafts. I have new oil pump and lifters and push tubes are open but it is so dry the top of valve is even wearing. I installed a new set of Comp. 850-1 and thought I had my problem fixed. I am going to try a Baisley spring but I was sure my pressure was ok before. Any suggestions? I also checked the breather hose for being open.
