I know this has been beat to death, but with time comes changes. I know Rollmaster was the one to get but recently I heard their "new" (ever since they got bought out) timing chains are under par and had some failures. Dont know it this is on all Turbo Buick engines or just stage II engines, but either way I would like some info. What timing chains are highly recommended and durable? I have a stock 109 block and looking to upgrade timing chain. Also what else besides the gasket is needed (ie cam buttonm etc)? Im pretty sure I do not need a tensioner right? Thanks guys!
