1.6 Rocker Arms In 89 4.3 will they work?

I have A rocker arm ticking in my truck and I was thinking while I got it apart maybe 1.6 rocker arms might be cool. With more lift and duration it should give me more power???? Will the valves hit the pistons???????????? ouch, dont wanna buy new heads!!! How much performance increase?? Is it worth $120-150. Jason

<font color=purple>Can't tell you about whether or not you'll have clearance problems. That'll have to be checked on-site. The 1.6's will give you more lift, but not more duration. You should have more power, but at a higher RPM. May or may not cause computer havoc. The increase in lift is directly proportional to the increase from 1.5 to 1.6. Multiply your current lift by 1.06666 to find your resulting lift.</font color=purple>

I just ordered roller tip rockers for 120.00 for my truck. We will see if it was worth it?
