You dont polish intakes, you port them. Unless you've done major headwork there's no reason to port the intake either, it more than likely flows better than the intake ports in the head.

Lol I appreciate that. I guess I'll be more specific next time. I'll post a picture of it when I'm done polishing it.

Does look nice. Has anyone here tried ZOOP seal? It's applied to polished parts and keeps them looking nice and easier to clean. Supposed to work well.

Taken quite a bit of sanding started with 80grit stepped up 100 grit at a time ended with 1500 then bought some buffing bonnets at harbor freight to do the hard to get spots because the sharp edges on the flanges tore em up, I use red polishing rogue an finish off with white. I've heard good things about zoop seal but I've never thought of getting it while I'm at the store.

I feel your pain! :D

It seemed that the more I polished, the more casting imperfections that showed up. I did similar - starting with 150 grit. I stopped at 3000 grit and then went to cloth buffing.

It looks OK in the mock up. Not perfect, but better...

Yeah I never could sand all the imperfections out but that's how it goes I guess. You look like yours polished out really well.

Same here - your's looks very nice, and I KNOW how many hours are involved.

I would just say to anyone considering doing the same - figure a good 2 full days, and maybe then some, depending on your level of obsession...

I think it knocked mine out of the "sleeper" category, unless I keep the hood shut.

Spent some time in the shop today finished up with the polishing, couldn't get it to polish to a mirror but turned out pretty good anyway.

It would take me another 2 days, and 1/16 to 1/8" of additional grinding to (maybe) get my Clif to look that good.

Very nice! :thumbup: :thumbup:

Thanks for the compliments, I had a hard time getting it to shine there is still some casting pits in it but what I found to really to finish it off was some flitz polish on my bench polisher.

WOW! Just when I thought I had all my painting and cosmetics done! I am now going to try to polish up my EFI intake, which will be a lot harder since there are more bends and small crevices. What type of polishing wheels did you use? I have the Harbor Freight conditioning kit that has 80 grit up to 180 grit wheels for a die grinder. I also have the lamb's wool polishing wheels for a die grinder. I started messing with a broken intake I have and got a decent shine using tripoly (brown) and following that up with white compound.

I need to find a finer sanding wheel, I think that will help a lot.

It's quite a bit of work, I bought one of those kits from harbor freight it's a good start but you'll need to sand it at least down to 1500 grit then start your polishing, I use zephyr pads on a bench polisher start with brown polishing rouge ending in white roguethen do a finish polish with flitz.

Waiting for my engine to get back so decided if it's aluminum it's getting polished. Fuel pump block off plate, intake manifold heater plate which not sure if will be needed and a slightly modified timing gear cover.

Looks great, But tell me is the name worth keeping ...It would be easier to polish if the letters where removed and I think that the larger smooth area would look better.

You must be talking about timing marks? I kept them thinking I was going to need them but after my balancer showed up not sure I will. I agree on a flat smooth surface would look better.
