Jon Ray ran a 15.49 @ 88 with his '91 Mustang.

How hard is this project and what does this task entail? Can I just take off the valve covers and slip out the old with the new?

Ouch, on second thought I think ill pass since the price is not worth it for my car. If my car was not terminal I would have gone for it, but the Intense website had nothing for a Series 1 anyway.

So how about the OR rods? Are they a good(as in real good) idea with 1.9'* and springs? I'm not looking to do a cam in the future. Probably only full exhaust and smaller pully.

Was that a 5.0 mustang, a 3.8 mustang, or a 2.3 mustang?

Oil-Restricted pushrods are highly recommended with any roller tip rocker arm. Roller rockers do not require as much lubrication so by restricting oil to them you help keep the oil in the block lubricating lifters and other more vital components adequately. Helps prevent valve float.
