Default RM H22 vs. JUN H22 Cams

What do you guys think, i have looked around a lot, and saw the jdogg dyno of the RM cams, and also saw his dyno of jun cams

https://honda-tech.com/zerothread?id=1077166 - jun dyno - 217 whp
it looks to me like more hp was still coming if he revved a bit higher....any thoughts?

cant find the rocket dyno on h-t but its on kteller.com link here - 179 whp
http://www.kteller.com/store/p.../1070

he had 8 bent exhaust valves with the rocket dyno, thats why it looks low

he fixed the valves for the jun dyno, so now i dont really have a definate comparison, theres too many variables to really draw any conclusion from this.....

so what do you guys think....and peak hp is not my only consideration, though it would be nice to have some big numbers up there....but im really concerned with midrange gains......some thick area under the curve and $350 for the set is definately better than the juns for $1500 with the valvetrain

so what thoughts do you guys have on some ballpark RM vs JUN numbers??

also, it says on kteller you will be ok with stock valvetrain as long as you keep stock rev limit....but it looks like that dyno peaks out at around 7600-7700, so i have two questions:

1)will the stock valvetrain be ok if i raise the rev limit to about 7800 on my hondata

2)will the stock valvetrain be ok anyway with these cams...aka has anyone been running em now for a while on stock valvetrain? if so how are they doing?

Thanks guys

the rocket regrinds and jun3 cams are so different that im not sure its worth comparing... its like comparing some skunk stage 1 cams to jun3's..

i would replace the valve train if you are planning on running any aftermarket cam.. yeah stock will work to stock redline, but what happens when you miss a gear... rocket valve train is good and cheap.. why not get it? i bent valves with type s cams reving to 7800 rpms on stock valve train..

i understand that....i think i phrased my question wrong....basically what im trying to figue out is what jdogg would have dynoed at if the valves were sound with the rm cams.....

i just used the two cams as comparison b/c they were dynoed in the same motor.....i realize the jun cams blow the rm cams out of the water....

the rocket cams would have probably been around 195-200hp if i had to guess
