I have Crane Gold 1.6 roller rockers on my 94, and they really make the car rev smoother, especially above 5000 rpms.

Go for it, make sure you replace the springs too. I read of 10 -15 hp gains.

With stock cam....will increase HP slighty...can't hurt....worth it....do you have the top end disasembled???

Then go for it......check clearance on valve covers...for oil drain back...should be OK..... :cheers:

How do you check the clearance from roller rocker to value cover?

its worth it. Get nw valve springs while your at it. Dont get the lt4 springs, theyre not needed and willrob approx.5-10 horse cuz of the extra pressure. Stick with the stock replacements. Guaranteed higher revving ability + smoothness.

Darn... now I'm confused... I've always heard that when switching to 1.6 rockers, that it was recommended to also switch to LT4 springs because they could handle the extra stress better than the stock springs....

With stock springs and 1.6 ratio rockers you will be very close to valve float, you should upgrade your valve springs just to be safe.

Go with the LT4 springs, the stock springs are within 0.020" of crush with 1.6 rockers and the stock cam. You won't lose any HP from them, they are very light, ~240# closed.
