tappet adjustment

Hi guys,

I have some minor tapping in my valve train on one side which I believe to be rockers on the valves. It's not too bad but I've been told that these can get worse and cause damage if left unadjusted. It's a big block 402 and runs very strong. I know I should look for bent pushrods and that the hydraulic lifters might be bad, but it is really minor and I think it can be fixed by adjusting the rockers. Can someone please walk me through the adjustment process?

Thanks in advance.

Dan
