Hello again!
As some of you may know I'm building an big bore b20 with a NOS big bore kit I got off ebay!
Most of it has gone together without a hitch! (you can see the progression here: BigBoreB20 )
But I ran into a snag yesterday. When I went to put the lifters in they seemed to fit into their bores in a really snug way. They didn't "drop to the cam under their own weight" like the instructions said they should. I didn't think that much of it since once the holes were properly lubed they seemed to move freely.
I proceeded to install the head and the rocker arm and that's when I noticed the problem. I wasn't able to set the lash on valves 3 and 6 because it was too tight.
I took the rocker arm on and off for the next couple of hours, switching around push rods, double checking to make sure the rocker arm wasn't torqued down too much, etc. Still, valves 3 and 6 are sticking.
Anyone have any ideas on what I can do to remedy this?

P.S. Eric at HiPerformance has graciously offered to look at it for me but I'm really trying avoid crating the engine and driving it down to him. He is nice and I am lazy.
