hey guys, i having trouble veiwing th picstures of the tute, i have recently bought one of these greddy copies, seens to be some burs on the inside, i'll just be filing them down n smoothing them out, apart from that the product looks good to me, smooth and should fit up nicely. Did anyone use a gasket or gasket goo when fitting one of these. i plan on doing the install soon. also could someone specify all the sizing of the nipples heater hose etc i need to buy. One more question.. with the ACC valve (thats the one on the left rocker cover, looking from front of the car right?) how did people block them off?
