Yes I am but I have a lot more cam than a 228R as well. 238/240 and .612 lift. The main reason for duals in my case was more of an experiment to see if I could make duals last a bit longer since my car is my DD. I drive back and forth to college with it. Unless you drive an hour or more with yours every day I would try to go with the lighter weight valve train as I ran into some valve float at around 6700 rpm with the heavy duals.

No problem. The 1518s are nitrided if I remember correctly so even though they're overkill with the .650 lift rating I would shim them up to that and let her eat. Let it warm up good before taking off hard (I let it get to 120* or so before moving the car, and stay under 2000rpm until its over 160*) and youll be fine. I almost wish I had done singles which is why I definitely IMO would recommend them for the 228R. Also just an idea on the first start let the car idle all the way up to full temp. Then let the springs cool back down i.e. one full heat cycle. Thats what a lot of people recommend for "break in" if there is one for springs.

Bump for mid January (the delay/anticipation is killin me).. Placing an order as soon as headers are back in stock..
Biggest pending question:
PAC 1218 or 1518 springs? I keep reading too many mixed opinions
As of now I'm leanin towards the 15s based on WhiteAw's (and others) advise but just want to make sure thats the right choice..

I ended up going with the 1218s on the 228r cam. There's a reason TSP recommends them with that cam (I even asked about upgrading to 1518s, they said the 1218s will do the job but the 1518s will add piece of mind) however in the end it's up to you to make that call. That cam is a .588 lift and the 1218s are rated for .600. To me that's a big enough gap. Now if the cam was a .595~.599 lift, it would be no question - 1518s all day long or duals.
Of course my opinion is biased as I made a pretty large order at once, and was trying to pinch pennies in the end (Well over $2000 between a cam/headers/intake/anything else that was needed for the install) and my train of thought was - if it breaks... make it better, faster, stronger!
