Sorry if something here already.
Since engine build been easyish on engine, but the other day running 70 on hyw floored to pass a truck heard loud valve rattle, tried again after truck just to see if I heard what I thought,it was.
Stock bottom build on 1964 225, have 1976 head decked 60 off with big valves. Now I used stock cam, lifters, rods, valve springs. And, atm a 600 holly on a super six intake. Should I have installed the heavier RV valve springs, or could this be a timing advance problem. Never knew solid lifter to rattle only at power demand, have had hydraulics float before. Any ideas? Thanks
