Thanks for saving me from throwing my wrenches!
The main reason the valley pan holes don't fit the intake bolt holes in the head is the block end rails were not machined down like they should have been.Intake only will fit with one .028 paper gasket
Can not get valley tin to work bolts holes would have to be hogged out.
Head seam to sit lower then the end rails on block by about.084 thou.
Not sure if cutting the intake here will help.
IF the manifold fits squarely against the head surfaces all the way around the intake manifold the pan ribs should crush down to the tin thickness of .015". Because the block rails are so high.....the pan has to distort around the juncture of the block, heads and intake and it is damn hard the get the valley pan lay down so the bolt holes line up....not easy to do with your unmachined block rails. It's why you take the block to a Mopar experienced shop that knows-what-they-hell-they-are-doing!So does anyone have a idea what a compressed valley tin thickness is? My manifold will bolt on with one .028 paper gasket but can not bolt it on withe just the tin .
I would like to run just the tin and Hylomar sealant.
I need to have manifold machines I just don't want to machine to much .
I am thinking if I can fit a paper and It bolts on fine. I can have manifold cut the compressed thickness of the valley tin and make this manifold sit nice and tight with out opening up the bolt holes. What do we think ?
Not too big a problem, done this many times.So does anyone have a idea what a compressed valley tin thickness is? My manifold will bolt on with one .028 paper gasket but can not bolt it on withe just the tin .

Do you have any pictures that is why I started the post. But guys are saying that the metal one they bought keeps on developing oil leaks.U can just use the paper gaskets then make a valley cover out of an aluminum sheet. That’s how my 470 stroker was done. Kim
Can use high spot dykem, a little goes a log wayWhen your ready to test fit put a light coat of prussian blue on intake surface. The prussian will transfer to heads. Needs to be carefully done, it doesn't dry fast like dykem blue. Wear gloves and have paper towels for clean up. It's what artists use. Prussian is available on amazon or where they sell art supplies.
Hello Jackpot50 I wanted send you PM but I can not because your PM box is full. Can you clean it please ?Can use high spot dykem, a little goes a log way
