440-6, 8yr old build, stealth heads, stock manifolds, Lunati 60303 cam/hyd lifter kit, 10.2CR. Brad Penn 15W-40 with Wix 51515. Starts and runs good, except for moderate rattle noise at cold startup. Rattle goes away after 5-7sec. Oil pressure approx 35 at idle, 60 at cruise.
Before I yank the intake to check the lifters, should I try different oil/oil filter? I did try a 1/2 quart of Marvel, no effect.
