Hey Fine Folks. Im in the middle of a Intake manifold and Gasket swap on my 2000 E350 5.4. Im leaning on spending the extra money for an OEM manifold rather then the doorman replacement due to some neg reviews on the doorman....What a reputable place to source this thats not a dealer. so many online stores that all seem like they are the same with super bad reviews.

Also, is both the left and right gasket the same part number?

TIA
