Questions & Answers Ask a Product Question

Will I be able to use these rocker arms on stock LS3 heads? If so, will the stock valve springs be able to take the added lift?

Asked by LOGAN on February 22, 2018


Thank you for your question. The Chevrolet Performance 12579615 rocker arm is not compatible with an LS3 cylinder head. However, we do offer a COMP Cams part number 1678-16 in 1.8 ratio that will fit your heads and the factory valve springs.
