Big Block - valley pan vs valley plate

Whats the pros/cons to running a valley plate vs the old valley pan?

First question: What cylinder heads?

For the average person you want to run what you need to run. That is, standard type heads should use a valley pan while extended runner heads should use a valley plate.

Currently have 440 stealths, but have TrickFlow 240s on the list for Santa...

Those are standard port heads so they work best with a valley pan. I designed a solid valley with batwing gasket holders for the TF 240 heads so I could get the port match perfect. It isn't really needed for a normal engine but I was trying to make as much power as possible.

I have cnc stealth heads , port is bigger than pan and felpro gasket . currently I use the tray etc opened up by hand . But it still pulls a little oil into #1 port , got the others sealed up second time round. I have a set of Andy's batwings and some Superformance gaskets on the way , I will use these with my home made valley plate . Hope this will stop all oil pull through

Yep, that is a common problem. I designed my batwing gasket holders just for the CNC ported head issue.

look forward to using them Andy

You won't be dissapointed, they work well.
