Prferrably this engine will have sat overnight to get "cold". Unless you can be assured that the engine casting temps are under 100deg, that engine cannot be reliably called "cold". Also, keep in mind that clearances should be set differently with aluminum pushrods as opposed to chrome moly steel pushrods due to thermal expansion differences. Also, beware of problems with valve seats. Assuming your motor has hardened valves and seats, it is entirely possible that your valve seats have pushed farther into the head. You may be getting ready to "suck a valve seat". Just my $.02 Scott __________________________________ Yahoo! Music Unlimited Access over 1 million songs.
