More info? (prices, options, performance gains, ordering time frame, etc) Or are we waiting for more people first, before we get too deep?

I'd like to see how many would be intrested, what they would like in a rocker, how much they would be willing to spend, etc. Once I know that I can see what direction I want to take this.

Roller tip rockers are not really needed for 99.9% of the Series 1 croud.

1.) Modified will be alot cheaper then roller rockers.
2.) Modified will not need stronger springs and new retainers.
3.) Because they do not need stronger springs and new retainers the install will be easier and cheaper. (If springs need to be changed they will only have to be replaced by new stockers.)
4.) Because they don't need stronger springs they will cause less strain on the timing chain and dampner. (I think this is a big + since alot of the series 1'* have a 'few' miles on them.)
5.) 99.9% of the series 1 cars don't make power with high shift points so their is no advantage with roller rockers and stronger springs. Even if the series 1'* could make power with higher shift points 99.9% of they wouldn't have a way of shifting higher.

Because of these reasons I think modified would be our best bet. I'm sure I could get modified series 1 rockers made for less then $300 as long as people show they will buy them.

What about for us who have the older designed rockers? Would just modifying them be enough? (I heared that the design is less efficient and less reliable?)

Don't worry about it - It'* simple to upgrade your valvetrain to the '93+ valvetrain.

What ratio are we looking at? With what you're saying those of us with higher mileage (135k here) should be able to keep the rest of our valvetrain stock? I had to replaced a bunch of parts when I had to replace my "cam interrupter" (magnet) so I do have a brand new timing chain and dampner, I'd just be worried about the old springs. What is this upgrading to the 93+ valvetrain? What are we looking at for performance gains? I know my NA will probably be less than your SC numbers, but some general idea. Lastly, are there any "needed" mods, what I have is in the sig. And soon a 180* stat. All sounds great so far!!

No other series 1'* would even think of rockers? If this is the case I'm just going to get a set for me.
