Default Drip tab removal question

I need to get the drip tabs cut down on my valve covers this afternoon, but don't have the heads right now. I'm using the crane gold series 1.6:1 rockers. Can anyone tell me which tabs need to be cut down and an estimate on how far. I don't want to wait until the last minute to start cutting on them, but I can trim them up to fit perfectly later if I didn't cut off enough. Thanks in advance.

On my '92, I had to cut them all, right down to the base. I also ended up having to skim down the tubes that inclose the valve cover bolts, as they were rubbing.

Yeah, and don't get lazy and try to snap them off or you'll likely end up with a hole in the cover where the tab used to be.

I would try to trim them as close as you can.

The 92 uses a magnesium valve cover so you can break them off easily if you cut them slightly. I don't think I would try it on the plastic covers though.

Exactly the same here. Cut/grind them off flush, then narrow down the bolt tubes. If they are magnesium watch out for flare ups when grinding/cutting, the dust is flammable.

Here is what I did. Grind down all the tabs naturally, then grind the tubes on the sides that have the RR nearest them. Then if there is any webbing to the bolts tubes I had to cut huge notches out of them, otherwise they would hit the RR. Especially the pro mags, they have big old fat bodies at the pivot point.

ncider, use a dremel to score the drip tabs, then you can snap them off. If the bolt towers need shaving, you can do that after a test fit over your rockers. Here's a link to mine when I did them:

Good luck! :cheers:
