Are they pedestal or stud mount rockers? Sounds like they are too tight or you have the wrong length pushrods.

Perhaps the bolt was torqued down too much which compressed the spring = left valve somewhat open.

did you dab some grease on top of the valve, set the lash, then pull off the rocker to see if the pushrod length is right?

I had this problem also. Pushrods were too long (valves were not closing completely). Comp Cams makes/sells an adjustable pushrod that allows you to find the right length. Summit carries it for around $25.00 and it saves a lot of time and headache. Chances are: new heads + new cam = new pushrods. The crazy thing with mine was that cyl. 1,2 had over 100lbs. of compression and the rest had under 10lbs. Heres a link to help http://compcams.com/Technical/Products/Pushrods/
