I have a set of LT1 composite valve covers that I bought to fit over my T&D shaft rockers. I done some research to learn that the drip tabs would have to be removed to use them with stud mount RR's and the LT4 valve covers didn't have the drip tabs. I done a little test fit with the passenger side cover, the one with the PCV valve hole. There is some support webbing/baffling on either side of the PCV hole and one web just off center. The drivers side cover has 2 support webs in it. These webs will have to be removed along with the drip tabs for these covers to have any chance of fitting. My question is will they fit after I remove the webs and drip tabs? If not I'll sell them and buy aftermarket.
I really want to use a stock type cover if possible

Most of the hard-core racers are long gone from this site.... a handful of us are trying to keep it alive..... mostly helping newer LT1 owners.

Have you tried ltxtech.com ?

That's where you are more likely to find help.
