[hypersnyper6947]

I have a wiseco 440 kit that i am putting in with 11:1 compression and i was wondering if heavy duty headstuds were necessary?

studs are very necessary, my brother inlaw had to rebuild a 440ex 5 times in 2 months because the guy kept blowing head gaskets cause the engine had the factory studs and that wouldnt have happened if the guy wanted to spend the money to do the build right... so YES get the heavy duty studs!!!

[hypersnyper6947]

heard that. Head studs it is then. I want to build in once and then ride ALOT. Any suggesitons on what bearings i should replace during my rebuild?

[Marc]

if you think there are any bearing that needs to be replaced then i would replace them

They all seem to spin freely how else can i tell??

[Marc]

if you can jiggle them side to side then its time to rplace them
