I got a torquer v2 cam....Can i go with the 1.8 ratio rocker arms?
dont they just increase lift?
Is it gonna cause clearance problems?
Think there will be much gains on it?

Looking at the cam specs in your sig, with the higher ratio rockers, you'll be over .600" of lift. You may need new springs, not sure though. You are probably running applicable springs with your current lift since its so close to .600". However, you may have valve-to-piston clearance issues. If your not sure, call TSP, they'll know.

Yeah, the stock 1.7 rr's should be fine.

will there be any gains from it?

From the 1.8rr'?
Sure, probably a small gain. More lift, more air.

You want to watch the ramp rate on that cam. You shouldn't run 1.8 ratio rockers with aggressive ramps, lots of stress.

If you want to get a bit more power, get some 1.7 ratio roller tipped rockers like Yella Terra makes. Not that expensive, and anytime you can put a roller in the valvetrain like that you reduce a good bit of stress.

More importantly, you won't have to worry about the bearing caps coming out on the stock rockers and letting the needle bearings fall out into your engine. There are a total of 1056 needle bearings between all 16 rockers. I don't think you need to ask me how I know that.
