I hope you upgraded lifters to OE-Rs (unless you actually have done a solid lifter conversion) as they will give you a great chance of acheiving a short travel preload on the lifters. Not slandering you but when you go all out everything becomes a custom scenario as for what fits where and most of us learn the hard way. You mention that longer push rods were needed? I would imagine that the S1X NA cam would have a reduced base circle of around 0.040'- 0.050' and considering you will be running approximately 0.523' with 1.6 rockers or 0.556' intake lift with the 1.7 rockers then different length push rods will most likely be needed.

The rockers were designed with this in mind and considering that the heads need to be tapped to take a larger thread I find your complaint abit out of proportion.sorry but that's the way it looks to someone that knows a little bit about the product you are bagging. In an application such as this (assuming it's an all out type of build) you would most likely have custom valve covers anyways to accomodate the rockers. The only application IMO that these Platinum rockers would still be relevant are in a race only set up that has a solid lifter conversion done. These rockers were deemed obsolete some time ago and were replaced by a much lighter an smaller bodied rocker called 'Ultralites'. Your complaints may be warranted but keep one thing in mind.
