Do I need to rebalance my engine assembly if I use lighter pistons (Hypereutectic Speed Pro Pistons)? I heard that is pistons are 10% lighter I have to do that. Is this true? I am changing pistons/rings/bearings/hot Cam kit/timing chain set...
Thanks
ps .What is the best method to instal valvel steam seals?

AFAIK, balancing is not mandatory at any time.

Some other advice-You might want to try to observe forum rules of one TTT per 24 hours. Posts that get TTT'd a lot by the author tend to get less posts instead of more.
I also think that you cause limited responses to posts by sticking a person's name on it (like mine ). There are plenty of competent board patrons, some being well versed in certain areas (ex. engine building).

 

But you are the best .....I know I wasnt suposed to do ttt so quickly, but I am starning my rebuild tomorrow morning and I neeed that info...
Thanks

 

I would have the rotating assembly rebalanced.

Shoebox is correct - I didn't read this thread at first because it was addressed to him. Then I did get curious.

What is the cost of doing that. Do you know any good place in NYc that do that job?

 

Sorry, not in the NYC area. It shouldn't be too expensive, because you have gone to lighter pistons. It's more difficult to add weight which requires the use of expensive "mallory metal". Maybe $75-100 or so.
