just went out in the garage and looked...

the two LA standard head bolt pattern heads have the 893 casting....and the brand new in the box W5 intake has the 893 casting...

so you can not just go my the casting number..the intakes appear identical except for the bolt pattern...

this intake is setting on top of a set of eddy heads...and the standard LA intake gaskets line up.

same casting ...different part numbers...
but the part numbers are not on the intake only the casting...
