    Default 1.8 Rockers too big for cam?

    Hey guys i have ordered a cam for my vx its a comp 224/230 114lsa . And i have comp 1.8 Rockers to go in at the same time. Now i have been told on another forum that this cam Will have too much lift for the Rockers to be used safely. Has anyone used this combo and what were results of it?
    Only people who have had experience with this reply please.
    Cheers Corbin

    What lift is on the cam, the 224/228 came with several variants of lift.

    Anything over .585 lift may become too big with 1.8 rockers.

    you should never use high ratio roller rockers with a large cam it throw your geometry out and will put side load on your valves and push rods.
    If in doubt......FLOOR IT!!!

    Will it work? Yes. Will you gain anything from going extra lift? Probably not.

    I don't like running springs that close to coil bind, but it should work. If for some reason it did fail and you did break a spring, the results would be catastrophic, so keep that in mind.

    As for the earlier post about geometry and valve side loading. Yes, that can happen, and likely will happen, but doesn't HAVE to happen.

    ANY changes to the valve train can alter rocker geometry, which needs to be corrected with the use of different length pushrods and/or shims and/or maybe even adjustable rockers. The installation of higher ratio rockers is no exception, geometry should be checked, preload should be checked, swipe should be checked. All of these issues can be resolved by the correct use of the components previously mentioned.

    You'll also find that valve side loading isn't the end of the world with factory heads. Sure, it isn't ideal, but it isn't really going to cause any short term damage unless you had aftermarket heads with bronze valve guides, etc.

    Oh, and also, I am just some guy being a smart arse, as seen in my sig, but I do also know what I'm talking about
