pushrod clearence issues
well I went to adjust the valves on the new 327 engine i built and #3 and 6 intake pushrods need more clerance thru the 292 head. i checked it and did it before it got to this stage. i don't see what changed. anyhow. anyone know some trick , you don't have to take it all apart again , way to open up the pushrod passages a little bit. I think i'm not going to bother with it till next week. enough already.

Are your rocker arms the new kind that self center on the valve?

Theres only one way to do it right 
You have to take the head off and make clearance with a die grinder or take it to a machine shop if you need more than .060". You run the risk of breaking through so be careful. Good luck Chris

if the block isn't all oily, it will stick fine and catch everything.

so what does this all mean.
one of the pushrods.
the 3 and 6 cylinder where the ones that where rubbing, whats this mean.
i also found the inside to be kinda grimey. think I'm going to pull it all the way down and do it again.

This is the engine you ran for 20 minutes?
I assume you are referring to the brown stuff on the pistons, i figure those are 3 and 6, correct?

Well, heck, dude,
making some logical assumptions, i don't see any need to tear the whole motor apart.
Pushrod 3 and 6 were rubbing, cylinder 3 and 6 have unburned crap on the pistons.
Free up pushrods 3 and 6 and problem will most likely be solved.

Valves are hanging open, just clearance the heads. BTW I would open them( all )while you have it apart.

I ordered the special tool from summit. Cleaned out the valley real good, checked the cylinder walls etc.everything seems cool. Guess I'll just wait for the tool drill ALL the intake pushrod holes and reassemble with newe intake and head gaskets. . All good fun.
