Installing new valley tray

I'm with 68383GTS, Never used the paper gaskets,just the tin with either Iron or aluminum.

I have tried it 3 ways, all with an aluminum intake.

* Gaskets at head, valley tin, gaskets at intake. Port and bolt alignment sucked.
* NO gasket at head, valley tin, gasket at intake. Port and bolt alignment better.
* Valley tin only. Port and bolt alignment perfect. NO vacuum leaks. :cheers:

I'll skip the gaskets from now on.
