i put the 1.8 rockers on my 402 and there isnt any clearence between them and the head. I was wondering if anyone else had any problems with them and what to do.

 

Some of them require machining the heads for clearance. Sometimes you can do it with a file or die grinder. Did it say that you'd need to? Might want to call them up and ask.

I'll move this to the internal section, you'd probably get more help in there.
