As fast68plymouth mentioned above ,if you truly have enough piston to valve clearance, try a couple of Hughes 1.6 rockers randomly and spin it over and recheck the clearance as the adjusters are moved closer to the rocker shaft on 1.6's. I been through this with Victors and B3 correction kits. Only try this if you are sure you have the piston to valve clearance, valve guide top tobottom of retainer, not going into coil bind on the valvesprings. No sense trading one problem for another engine damaging problem. Check and record everything first. Really helps when you are in this situation. Bill
