Well I just bought some shaft mount ones from a guy on here for 300. I hope these will be fine. What do you guys think?
I was not going to buy the ones on ebay, it is just a short cutt to what they looked like, and all.

If they are lighter isn't that a plus?? Or are they heavier?

They seem to be ok in mild applications, but aren't so great when you need to turn some rpm's. YT also came out with a "lighter" version of their rockers, but I've yet to see them tested.
I answered most of that question above. The Rockers are heavier than the stock pieces. If you make sure to buy good parts in the begining, you shouldn't have any trouble. If you are gunna run the aftermarket rockers, make sure you get a good spring! Skimping in that area will surley cause you problems sooner than later.

I have a question,
You guys are talking about how heavy they are on the high rpm side, Is it possible if you can machine some material off of them to make them lighter. Would that be a good idea or is that just out of the question????

According to yella terra in AU the new ultra light weight rockers are lighter than stock and are lighter on the valve side of the trunion.
I have asked several sources including YT for some real data such as the weight of a set but have not gotten anyone to provide that answer yet. It would also remain to be seen what the actual weight on the valve would be as no one seems to have this information either, just statements as above without data to back it up.
If in fact these rockers do turn out to be lighter than stock in total weight and across the valve side I would buy them. Hopefully as more people get them, more information will come out. Jub Jub seems to like them and thats a plus to me but I will need to see more yet.

I installed a set of the new style YT's last week and have no valve float issues. I was worried about getting needle bearing in the oil pan with the stockers and was originally going to send my stocker to HS for the upgrade.
Then I saw where Tony Mamo of AFR had used the ulta lites on a couple of his recent motor builds. I know he does spend alot of time on the dyno with his motors and only uses the parts that he believes in. That was good enough for me. Plus the YT's are only about $100 more than the rebuilt stocks but you get a roller tip, huge cross shaft for stability, and no more needle bearing in the oil pan. It made sense to me to go with the YT's for the peace of mind.
