hey guys sorry pretty easy stuff but my first cleveland, have the stock manifold off and replacing with a weiand xccellerator, now the stocky had a tin gasket pan thing under it,it was in not so great shape, do i need to use this when i put the new manifold on? or does the new one just fit up to the heads and block with gaskets. bit confused as to whether i refit this as if so i think i need a new one.
thanks

also in the centre 2 bolts RHS there is a opening,think it flows exhaust from one side to other, do i just make up a lid for this to keep it in or does it require something else

just block it off with a plate.
its for the polution gear on later models

dont think that the tin plate is that expencive ( used to be about $25 , but its years since i had to buy one )

you will proberly get a lot of mixed opinions on whether you should use one or not.( i always fit one )

i believe the main purpose of it is to keep the hot oil off the bottom of the manifold. kind of a heat shield.

ok thanks heaps,yes i just blocked it off with aluminium plate. was told $70 bucks for the tin plate and kinda screached at that, but maybe i was getting ripped..just dropped manifold into place and it needs something to fill the gap in there so i think i'll track one down

[blocked the hole off with aluminium plate that is

Yeah, the home made aluminium plate works a treat.

As for the valley oil pan.......some fit them, some don't. I never have, mainly because I've never had one in my motors. As mentioned they keep the hot oil off the bottom of the inlet manifold which keeps it cooler. This allows a cooler, denser charge of air and fuel going into your cylinders....which = more power. That's the principle anyway, as to whether it makes a real performance/economy change, I think you'd be splitting hairs.

If I had to spend $70 on a new one.......I'd be getting cheese burgers instead :hy;

Fel Pro do the Intake kit with the pan + gaskets + glue. I bought 1 for a 2V cleveland, it cost about $38.00.
