I'm currently using 1.6 rockers from comp cams. I've had them on for a few thousand miles so far without a problem.

Comp cams, Scorpion, Harland Sharp, GMPP, Proform.

You will need Narrow body center bolt. Iyou get no self alighning you will need guide plates.

Valve springs can be hard to pick sometimes. There are alot of diffrent brands. I would suggest a patriot spring myself. There is also beehive, comp cams ect... I would skip the lt4 Springs and get a better set.

X2 I've never had any lt4 springs myself, but from everything I've heard on here, they suck. I'm currently using comp cams beehive 918's, which have worked without any issues for the past few thousand miles.

Ummmmm not sure who Alex is or who males his springs but in my opinion if you don't want to deal with BS stick with a.company that has been around for a while. EX.comp cams or Pad Patriot and so on. 95 seems like a good deal but that's 1/3 of the cost of a real good set of springs. You get what you pay for.

What would be the difference 1.6-1.7s on a full bolt on car and what about when I do a cam?

I have seen every kinda rocker made break before. If you stress anything past its limits it will break. And I have run a set of the same scorpion rockers on 3 diffrent motors without one issue. I have had a comp gold break into 2 pieces after 5 passes. Seen a promag break in several diffrent motors. So everyone can say a particular part sucks or stay away from this or that. If his buyer is low witch is a common situation these days then some have to but the lower end stuff. I would say proforms do suck and the quality is not the best but they work for some. Aluminum rr are not the strongest to begin with anyway.

about 5hp and when it's time to cam, you just take the extra lift into account when it's specced.

Corrected. Not worth losing a motor over cheeping out on valve train. Keep your revs down until you fix the problem.

That really depends on the motor. Some circumstances will show zero gain. Some will show adverse effects. I'd say for most 5whp is a good generic bet.
