I am upgrading my cams from the skunk pro1's to pro2's. I have been running the pro 1's for about 15k miles and havent had an issue but wanted to get a little more out of the motor. Currently the pro1's have been degreed and I am using the pro springs and retainers. My question is, will it be safe to simply install the new pro2's and drive the car? I will obviously get retuned but should it be safe to drive if i stay out of vtec? Also, what should I do with the cam gears, keep them at the same degrees or move them back to 0,0?

Edit: I forgot to mention that im running a 84.5 block with rs machine pistons.

 

Skunk 2 has "quick settings" to install their cams at which should be relatively safe assuming your motor hasn't been decked a lot or had a crazy amount milled from the head. I would not run the pro 2's at 0-0.

 

the block was decked slightly and the head was milled slightly only to ensure a flat surface.

 

Drop in and go, make sure to reference the Skunk2 settings before turning over the motor. The recommended centerlines are different between Pro2 and Pro1.

I did not degree in any cam I've installed on my motor, just made sure clearances were good and understood recommended centerlines versus OEM.

I always state this, the degree-in process for camshafts is good practice, but if you plan on tuning cam timing, it is a moot point. Just be sure you know your limits for V2V and P2V, V2V being the most critical with Pro series cams.
