I'm helping a young (21 yr old) enthusiast new to the hobby with some engine issues. He added Edelbrock aluminum heads to a 440 and now he wants to put on a Weiand aluminum manifold. I've never messed with aluminum heads, so I'm unsure about the gasket situation. Does he use just the valley pan gasket and brush on the tacky sealant stuff around the pan gasket (and rtv at the corners) like I do my steel heads and aluminum manifolds or is this the time to use the additional gaskets that come in the set?

Depends how much space there is which in turn depends on if the heads/block/intake have been milled or not.
You have to mock it up to see and then go from there. I always mill the intake side of my cylinder heads so I can use a double paper gasket but most people don't do that.
To do it correctly the head and the block should be milled so you get a three way match at the top of the valley rail. The cylinder head, deck surface and valley rail should all meet at the same point. Lots of guys never check that which is why they have problems with the intake leaking.
I'm tracking with ya - I'll put the manifold on with no gaskets and see how it all matches up bare - then determine if the paper gaskets are needed. Makes sense with how you explained it, thank you.

we've ran with no paper gaskets, with only one set of paper and with both sets of paper. Just depends on how everything lines up.
Roger that, thanks for the feedback. Made total sense when Andy laid it out like that in layman's terms!!!

The hot lick is to use the paper gaskets that are available now in .015 thick( not .030 each like Fel Pros ) making it easier to use one on each side of the pan..but the coolest trick is use Holomar around the intake ports--I mean... I use RTV at the ends and up to the first bolt hole--You have to--never a leak but...fuel kills RTV so you turn to a product invented by Mercedes (I think) called Holomar--a blue goo that is NOT affected by fuel or oil or temp it will seal up around intake ports like a bank vault

Doing that for over 30 years. No adhesive or sealant on the head or the intake. Makes intake swaps a snap.

My old 451 engine with the B-1 B/s heads and M1 intake, I had to have 0.100" taken off each side of the manifold. I think the block may have been milled down, not sure about the heads, but that is most I have ever had to take off to get an intake to fit.
