Indy heads, RB block

Part No.: AR182

Price: $250.00


This billet valley plate from AR Engineering fits any Mopar RB block that is fitted with Indy cylinder heads.  The plate is 0.375 thick with two large windows cut out to provide access to the lifters.  The center plate is made from stainless steel and can be removed while the intake is still in place for inspection or camshaft replacement.  Unlike some other valley plates on the market, this plate has machined edges so only a thin skim coat of silicon is required to seal to the heads.  The machined edges are designed to fit properly on a block with 10.72 deck height.  If your block has been decked a large amount then the edges may need to be trimmed.  Bolting the valley plate to the block while decking the block will produce a perfect fit that will seal with very little RTV.  The AR182 plate may also work on Hemi engines using raised port heads such as the Indy 426-1 heads.  The AR346 clear center piece can be installed for dyno testing.
