Joe,
I have the GP3 cam with 1.65 rockers on my car. No problems with
drivability, and this is a street-driven car. In fact it was my sole
mode of transport from May-Dec 1999 and May-August 2000 (while on
internships), with these mods, and I would estimate I did about 15K
miles during that time. I am running 9.5ish compression and did not
need to make any push rod mods. And as with all of the Goodparts parts
that are on my car, I am very happy with them, but wish (as RML stated)
that I could get a transparent valve cover so that those beauties would
be more visible!!
