Will I notice a difference if I install 1.7 roller rockers?

So far my mods are 52mm Fastman, Headers, Gutted Cat, FlowMaster muffler, and dumps.

Thanks.

I would think so, your adding more lift without changing the cam. You'll probably have to gut (baffles) the stock valve covers for clearence.

if you would have taken the time to read the tech link posted you would have read this :roll:

A comment on Roller Rockers:

You may notice that we remove the stock guide plates and did not reinstall them or any aftermarket ones. You may also note that some other manufacturers offer kits with and without guide plates. Some companies recommend using guide plates if the engine is going to run over 5500 rpm while some simply offer it as an option for those who want the extra insurance. The reason for this is that at high rpm a normal stud mounted rocker may actually turn on its stud, effectively coming off the valve and pushrod. This can cause serious engine failure as the pushrod is then allowed to fly around in the head and possibly take out other parts of the valvetrain. The guide plate prevents this by holding the pushrod in place and only allowing it to move up and down as it follows the lobes of the cam. In our case, the Harland Sharp rockers are paired together (intake and exhaust) on a shaft. Because they are shaft mounted, they cannot turn on their stud and thus there is no need for guide plates.

i have been told by many to replace the stock valve springs when installing the roller rockers. Specially if the springs have 50,000 + miles on them.

Sorry buddy. Next time I'll look through the tech section first so I don't upset you. :bigthumb:
