erson rocker assbly question

[RICK LAKE]

wrench 87 The washers ( silver ) that come with the rocker assemblies are for stub kits where the black washers from ARP, rub against the rockers. The black washers spread out the torque of the nut over a wider area than the silver ones. This helps with Aluminium parts and cuts down on the groove marks on the mounting surface. As far as the oiling system I run .080 holley jets in my motor. You still need to keep the valve spring in oil to control the heat they make. .080 Holley jet just makes it in keeping the springs wet. I also believe in over filling the motor 1 quart of oil when driving. IMO. Make sure that the intake gasket holes for the oil return are CLEAR. Some cover up as much as 40% of the holes. This will cause the oil to have to return through the pushrod holes and take longer to get in the pan. Polish the return holes and smooth out the ports. On convincor head picture, IMO he went too close to the edge of the head on picture 2 and may have a sealing or oil leak problem. 1/8" edge is needed for a good sealing surface. On Aluminium parts for opening up ports or drains, I use only sand rolls, a grinding bit can get away from you and you grind off more than you wanted. IMO Rick L.
