Polishing intake manifold
If I wanted to polish just my intake manifold would it even be worth the time? I don't want to do any port matching and all that if I could get some gains from just doing the manifold ill stick with that also, not going for a MIRROR look finish either but if I can smooth out the cast marks and make it smoother inside might do that when I install the MDX spacer soon
let me know what you guys think

I think only a dyno would prove any gains as it's probably in the 5whp range from porting a manifold and runners, so nothing you would feel that much. If you have the time, I would smooth out the casting marks and gasket match the openings. Just flip the manifold upside down and place the gasket in it's proper place. You can scribe a line or use marker to draw on the area that will need to be removed. It's super easy and you just need a rotary tool with different grit wheels. I didn't go mirror finish either.

I just did this over the weekend. I used VHT wrinkle plus to give it a nice texture and also with the valve covers I used VHT wrinkle plus turned out really good
