Roller Rockers will increase your HP.. However - it's usually less than 15 - 30 HP... unless you change the ratio. If you go from 1.5 to 1.6 ratio - you'll increase the lift and also horsepower.. But 30 HP is not realistic
Save your money. Get a good set of roller tip rockers. These will fit under your stock valve covers. The rockers in stock form are about 1.48. Good rockers are a true 1.5 or 1.52 or 1.6. The Hp they are claiming comes from higher lift from the 1.48 to 1.5 or 1.52 rockers. You don't need rollers for a stock engine. Put on good flowing exhaust or an intake and you will gain more HP for your money
:iagree: If you are gonna change them, go with 1.6 rollers, they are like installing a new cam with slightly higher lift. Should give you a hp increase.

Just make sure that the springs can handle the extra lift!! My springs for example would coil bind with 1.6 ratio...
