LT4 composite valve covers not fitting...Need help fast. Well I thought my LT4 valve covers would just bolt on.
Wrong, there is an obstruction somewhere. I think its the thingy that hangs down and it is making contact with the poly-lock is. See pics.
I have a rather high lift cam with Comp pro-mag 1.6R roller rockers.
Anyone ever run into this problem. What do I trim? Gotta wrap this up tonight.

Is your alternator on? heh That'll cause it not to install.
Don't know what else it could be, I was under the impression the LT4 covers had more rocker clearance.

I am not sure, because I don't have those particular valve covers, but it seems you would just need to trim that piece you are pointing at. Maybe someone that has those covers will chime in.

Ended up trimming after making certain those things I am pointing to were the obstruction. Fit great now. I think the real LT4 did not use poly-locks, thats the difference.

If memory serves me correctly....
All Corvettes used plastic covers as you are showing. Those are not LT4 covers.
The real LT4 covers do not have the bumps inside the covers, in order to clear the factory rockers arms.

One more question guys.
When I cut these "drip tabs" off, do I need to prep the cut surface or leave it alone. Seems oil might soak into the cut areas. I know super glue would soak into the cut area and seal it up.
Any thoughts?
