Im using sidewinder heads that were milled down to 80cc on an rb block that was zero decked to the L2355F flat top six pack pistons.

With the blocked decked a little, plus the heads milled, Im worried the stock style valley pan wont fit right and Ill have to use a plate then a stand alone gasket on each head where the intake meets. The intake I will be running for now is a holley SD that will also need to be milled to fit.

Will a valley pan tub work just fine, or should I go the plate route? I would like to get the most affordable solution, but if I have to use a plate I will. Ive heard of many guys having issues with them leaking no matter what they do.

If you have a suggestion, please give me part numbers if you know them. I need to order asap

Thanks in advance!
