Default */C Rockers in a NA

Would there be any benefits; is it even possible?

I'm guessing that since the */c series 2 is a lower compression, then putting the rockerarms on a n/a would run the risk of a valve tap or a collison of the piston and the valves.
Not sure at all though so ya never know. That'* a pretty good idea.

Aren't they the same heads? I would think the rockers would be the same. You'd want High ratio rockers for a good benefit.

The */C rockers will work fine in a N/A engine, they just won't make as much power as the N/A rockers. The 1.9 ratio is just too high for N/A so they lose too much low-end torque. The split ratio (I think 1.9/1.85 or something like that) work better, and then there is yet another set of N/A rockers that are supposed to be even better, but the SC rockers will make an improvement on an N/A engine anyways. They are better than stock if thats all you're looking for.

Oh, I was just thinking because I saw some on Ebay for a SC 3800 that were under 100$.

I would go with the ones that were MADE to work in your engine. THat would suck to spend all that money and ruin your engine or not get the performance that you want.

They were like 50 bucks, and the performance I wouldnt expect that much, but they could screw up everything else. Just thought maybe there was a cheap trick to it.
