RHS or EDDY

Sportman - I see only a few posts from you, so if you've lurked a bit here you know we get 'tudey and no harm is meant by it...lol
If you want to replace your heads here's the short short version of my opinion...
- the RHS are the least expensive, but heavy, and if you do, get the LA type valvetrain because it's cheaper. These heads make decent power, and have a little potential in them with porting should you want to go faster later.
- The RPMs are more money, but once you have the two choices ready to bolt on, it's not much more money, and they are MUCH lighter, and have more potential.

IMO, if you want heads, the RPMs make a better choice if in the future you want to go faster/quicker. If you want to address an output you have now that either you got used to or is lower than you would have expected (500 miles aint much seat time...) then 1Wild is dead on. The cam is too small, and the carb is too small. By addressing these I could easilly see you finding another 30+hp for less than 1/2 the cost. Will X/J heads limit overall power? Surely. But IMO, unless you have a plan to go progressively faster, you can take this cheaper approach and get a lot more usable power right now. If you have a plan to go progressively faster, or do road course, or gymkhana or whatever, then the RPMs are a better choice. That's my mode of thinking anyway.
Never feel sorry for asking a question. The posters are all willing to help, even if there are alterior motives or instances where the info might be less than perfect.
