Nothing new here - this method of raising the shafts up using an offset cam insert was tried more than thirty + years ago - you will eventually find that you will either pull or snap the studs out of the stands or push the whole shaft over - the more spring pressure the more the design flaw will begin to show. The solution thirty years ago was to machine the pads and make new blocks that were located and pinned to the head - yes it was pricey but it worked with lifts approaching .900. On a mild - low lift motor this method probably works fine - its an age old argument with a single shaft valve train as to rocker path - but there are many engines running T&D, Jesel, HS that are performing just fine. Its just a matter of personal choice
Thirty plus years ago, roller rockers for a Mopar were not all that prevalent, and .900" lift was unheard of in anything less than Top Fuel. As far as today, with today's technology and parts availability, who in their right mind would use a single shaft rocker system with 900" lift. Seriously!
Again, everything has its proper application, and I've done the blocks when necessary, or desired by the customer, and ZERO failures to date.
On a side note, I was supposed to have a set of the custom rockers at Carlisle this week, to compliment the Trick Flow 270's I will have on display. Unfortunately, T&D will not have them here in time, even though I ordered with plenty of time to spare. It would have been a good opportunity for show goers to check them out first hand.
