Re: installing L89 heads at dealer, 68 camaro
Even with the few L89 cars that were built I heard early on stories about the rocker stud bosses breaking off and valve seats falling out, especially in race situations with heavy spring pressure. As far as installing aluminum heads, dealers would install whatever you wanted if you were paying. It wouldn't be considered a true factory L89 car though. Probably voided the 5-50 warranty.
