poured block

Its been awhile sinced i poured a block (it was a customers 400 chevy) and i cant find my notes as to when i poured it. I dont remember if i poured it before i bored it or after i bored and before i honed it.
If i bore and leave .003 to hone out do you think the cylinder will move enough to make a difference ? If i pour after i bore?
Anybody ever test this and have results?
Or should i pour then bore just to be safe?
Any way i used the moroso block filler . is there anything else out there that people are using now?
I have heard there was a hard plastic that you melt then pour it in,have you heard of this?
Thanks to all replies..............Ron

i never filled a block but i was gonna fill my 501 and i was told to do it befor i bore it
i have some rockblock i was gonna try

I'd use the Hardblok, then torque the heads down and let it cure. That way, boring with a torque plate will keep things niice and true.

I agree with Maverick's method, FWIW

I would torque the mains, but in my experience, the head bolts only really distort the top of the bore where the threads are next to. So if you are filling the block that high, then yes, but I imagine it'd run pretty hot. For what it's worth, I saw a super I6 that was honed first, then the customer told us he wanted hardblock, so we added it and it did not move the bore around at all.
