My head is off. I have purchased delta cams 264 weld and grind. The guy at Delta said I have to adjust my valves and tighten the lash. He says 0.006 thou on the intake and 0.008 on the exhaust side. He said I have to either lap the valves more or grind the valve stems to compensate for the difference. My new valves are .015 -.005 thou short.
Should I bolt the cams onto the head or can I just rest them on top and check the clearance between the lifters and the cam lobes? Will I need to remove the valve springs? I'm doing this all backwards, I just spent two hours putting the valve springs back in with needle nose pliers. Is there another way?? -------------------- |

I'm confused; do you have too much clearance, or not enough? Grinding the stems will increase the clearance, and lapping the valves shouldn't change the clearance at all.
Check your clearances as they would be with everything assembled (cams bolted down), this is the only way to find out which direction and how far you need to go (more or less clearance). |
