[Clearance]: Valve Covers & Roller Rockers
I snapped off the drip tabs in one of my spare valve covers today just to see how easy it is. I am going to use these when all the stuff goes on. Do you think that what is left of the drip tabs in the first picture will interfere with the 1.6 Roller Rockers? And how about the 2nd pic?

Hey scorp.. i'll tell ya now you need to go all the way with them (second picture). I just got done doing mine a few days ago. At first mine looked like the first picture, and they wouldn't even go on all the way. Grind them all the way off.. there's no need for them with the 1.6's anyway.
BTW, as you know, mine is an LT1, so the cover's might be slightly different in demension, but go ahead and do picture 2 to be safe...

Scorp,
Thats exactly what I did to mine. I just snapped them off with a pair of pliers. They fit perfectly with no extra grinding. The pics look good to me. I had Harland Sharp 1.6 rollers. They are a pretty large bodied rocker. Not sure which ones you have but they will clear I am sure.

No, what's left won't interfer. Actually only abot the bottem 1/2 half inch is in the way. I put my valve covers on and forgot to trim the tabs. As soon as I fired the motor up the first time , I realized that I had forgotten and got the crap scared out of me.
If anyone else is doing this, don't just reach in there and snap them off with a big honkin set of pliers. First take a Dremel tool and a cutoff wheel and score them around the point that you want to snap them off. If you don't you could snap out a hole to the outside world. :eek:
Take a look at some the indentations where Scorp snapped them off.
Scorp you will love the 1.6 rollers.

Re: [Clearance]: Valve Covers & Roller Rockers (STL94LT1)
Here is what I did to mine (before bathing). When I put them on like this (all cut to match the 2 that are cut in the picture), they wouldn't even bolt down.. they were about 1/4-1/2 away from sealing onto the heads. Had to grind them ALL the way off.

Re: [Clearance]: Valve Covers & Roller Rockers (scorp508)
Oh, I agree that they should be cut all the way off. That is what I did to mine. One was broken off at the base and left a depression into the valve cover, it looked like some in Scorps pictures; I think that you could see why I misinterpered the light area in his pictures as a depression. The rest that didn't break off had a marked intication of the interference points. By the way mine are the Crane Gold Race, self aligning varity. The valve covers did seat all the way down, well at least it looked like it :rolleyes: . The eye opening experience was worth more than a strong pot of coffee caffine high.

Re: [Clearance]: Valve Covers & Roller Rockers (scorp508)
Scorp, I'd take em down a little more. I took mine down all the way because I didn't want to take the covers off again. However I think I should have left a little to get some drip onto the rockers.
Also take some material off the sides of the bolt guides to assure clearance, it's pretty tight in there with ProMagnums (I'm using 1.6:1, 7/16" ProMagnums too).
BTW, are you going to use the MAD valve cover paint on em? It realy does a fine job of bringing em back to that OEM look.

Scorp: Just a thought on grinding them down, awhile back one of the guys in this forum recounted what happend with a shop rag that he had wiped up the magnesium particles with then got it to close to an open flame. Magnisum burns like crazy. And it is tough to put out :eek:

Yeah you might as well not bother unless you are going to cover it in mineral oil or somthing non-flammable like it. My dad has had the good fortune of witnessing a few magnesium motorcycle blocks go up in flames.

Re: (scorp508)
Scorp, You want to smooth them flush with the surface... in addition, you might want to run an extra thick valve cover gasket.... or in my case a double gasket.
btw, when is your project moving forward to another level ?
