OK I'm confused on MOPAR Tunnel Ram P4532175
Oh, if you’re porting it yourself, remove the gaskets and align it up as evenly as possible for the least amount of porting and minimal removal on all the ports. Keeping it symmetrical and easier. Just round the edges on the upper plenum into the base and contour downwards.
If you change the shape of the runner, it should only go wider and taller, or towards the cylinder head side. The floor will need epoxy. It should be fairly obvious to even a new guy on what needs to be done and where for that straightest line of site path needed and as much as possible.
Would you have a link to that linkage set up?
