Product ReviewsEngine Valve Cover Set-VIN: W, Eng Code: LS3, Natural Holley 241-113

Would recommend

I've installed these valve covers on my ls6. Great quality and nice red paint. I'd only buy it if you had the extra coin to throw away.

Lookgreat but Issues fitting.

The valve covers look very nice however I did have issues with them. The bolts sent would not thread into my LS 862 casting heads. The round coil packs will not bolt to these correctly. I have to fabricate a bracket for my coils and buy new M6 X 100mm bolts to get them mounted.Read full review...

not happy

The 4 valve cover bolts that go into the head were a different thread than the head. It was a stock performance ls3.
