My block is o-ringed and I'm gonna use copper head gaskets, probably Summit brand. I know it was mentioned that 'The right Stuff' and some RTV's were ok to seal the water jacket holes. I went to NAPA yesterday to buy the right stuff but was not in the mood to pay $21 for the small tube of it. So I bought orange RTV, will this work ok?

Yamabond, HondaBond, and right stuff are all basically the same thing and way tougher after they dry than RTV. You can use right stuff for a gasket and it is very tough to get off and with clean dry surfaces it is pretty much never going to leak I have used it for oil pan gaskets and not had them leak at all, also makes great intake end seals.

Is the Yamabond cheaper than the right stuff? Is it easier to clean off, or the same? Where is it sold?

i'll probably cop some crap for this but i use roofing silicon on my gaskets. it's high temp as i use it to coat header gaskets so they can be reused multi times, they seal the water jackets everytime no leaks & best of all a quick rub down with petrol or carb cleaner & they clean up nicely. 2 of my crew are automotive specialists & when i first showed them what i was useing they cringed. but 5 years later they are sold on roofing silicon. 1 of my crew was a hardcore "3 bond" user claiming it was the best(it's like yamabond) but these days i see he's opted for roofing silicon too. and the best part, it's dirt cheap! deit- just reading the label it says it's good for aluminium, copper, lead & tin & sticks to galvanising & powder coated materials. the price on the tube is $3.99 & thats our $ not usd.

1. It really is worth it 2. Stop being cheap.
I used Yamabond on the first 2 Cometic installs I've done, both with fresh aluminum heads. 1st one was sloppy, but it didn't leak (on a BB). Second one was neater but it leaked (on a SB). I'm... not going to be using that stuff again, it's really nasty to work with and hard to apply properly. The time it takes to properly apply it to all 4 surfaces of the head, gasket and block causes it to dry significantly in my experience. It's like working with a runny salt-water taffy .
Props to all that use it successfully, too much of a pain for me though .
