Well what do you know? Finally, and with much general effort, four tubes installed. First test drive was last night. Couldn't see if there was any smoke behind me, obviously, but running it in the garage after I noticed a distinct lack of the haze of blue smoke which used to rise and curl around the lights if I left it running in there. Picked up my son from his night shift this morning. Back window is not the cleanest, sun on the horizon. Bloody blue interior so the blue from the parcel shelf reflected on the hazy back window with the mist in the rear view mirror was always looking like blue smoke coming out but each time I would look in the side mirror and it was actually clear. Did the whole windy road up and down the hill to my son's work and back and nothing. A few small blasts on the short straight bits of road where I could and still looking clear. Back in the garage, give it a couple revs. Looks clear. I'm still feeling gunshy about saying this but I think it's fixed.

Thanks so much to everyone. If there's a small amount left I suspect it will just be because something is getting around a split in a tube that's in a bad place. But actually I think it's finally fixed.

TL;DR: If you break through to a head bolt hole on an Edelbrock head you DO need to sleeve. Also, if you take out the rocker studs you need to seal them.
