The rockers might help a little but for the money the gain per cost I wouldn't think pulling the heads for the 204's would be worth it. I love the cam'r-s because they are a great bang for the buck bolt in.

The rockers aren't helping much; maybe on peak HP by a couple. The first 95" I built years ago was done in phases. I did the Stage I first, then the 95"BB with SE204 cams and then addes a set of BigBoyz heads. The gain, in round numbers was 10HP/12TQ. It takes a gain of about 5HP/5TQ to register on the butt dyno so, yeah, it made a measureable difference. You won't get it done for $300 though as you will need to deck the heads about .060" to set compression somewhere between 9.6 and 9.8, whichever you are comfortable with; consult with Bean on that. I went for 9.8 and added compression releases for those hot south Texas summer days; don't like those nasty heat soaked hot start kickbacks. You need to use a .0030" MLS head gasket as well and you will have to decide whether to retain the OME pushrods or go with adjustables.

IMHO, it's definitely worth it.

I was trying to reply on my wifes Kendal Fire and my fingers are too fat to type. IMO it wouldn't be worth the money to pull the heads. If you have a good X exhaust system such as V&H's power duals, Fullsak or fuel moto's pipe with good mufflers and a great tune you should be in the mid 90's on hp and 110tq there about with the 204 cams.

I was wondering if 103" with .030 might be a bit too much compression with 204's? Static would be a bit over 10:1 if deck height is around the normal .003 in the hole? If you have to cc the heads to make the 204's work, wouldn't it be more beneficial to pick another cam for tuning sakes ? OTOH, last year I was talking to a reputable tuner about doing a 96" with 204's/SE rockers/.030 hg and head work and he thought that would be a very good runner...

Sure it will help, but IMO it defeats the purpose. The build you have now is bang for the buck. Spend yr money on a great tune or bling.

I missed that little detail, my bad. No decking and a .040", or a .045" will set it right. Of course, a good tune is required and I would be looking at compression releases as well.
