Not trying to stall your thread . Sorry......

Also I wasn't trying to knock anyone here... What I do know is that Baisley's heads are top notch and I'm not putting them down at all.......

I'm not a engineer and understanding flow studies can be misleading. What I do know though is the my Evo heads are flowing 161 CFM front cylinder head and 162.5 CFM rear cylinder head at 10"@.600 lift. Most likely more than enough for the street...

If you want want Baisley's heads for the street go for it. But you are gonna pay just make sure all the other components match the heads.....

Those numbers make more sense.. The low 160s flow is plenty for the street as long as the motor ain't too big but it really depends on where you want the power, target CR etc.

Baisley heads on a 117? Absolutely.. Like Paul Morris says, with Baisley stuff you are paying a little more but it's worth it.. Your motor will blow the 124 crate motors in the weeds and vibrate less in the process.

His head's will definitely get you top end without a doubt. Provide you have all the other proper (matching) components... Me I like low-to-mid and yes I like top end as well but all the real power is mid-range, low-end to mid-range for the street..

A couple of weeks ago I had my bike on the Dyno doing fifth gear runs (I have a 6 speed transmission) in 5th gear on the Dyno I was doing about a 135 miles an hour at 6200. 6th gear @ 6200 would be way up there. Honestly i'll probably never see that on the street. There's a lot to chassis set up when you doing those speeds. Not to mention the proper tires.... An H rated tire ain't gonna do it...

Every one is different. We all have our desires and if that is what you want then by all means go for it... Never second guess yourself and don't skimp. Do it right the first time...

And Yea, Paul Morris.......... That guy is in another zip code..... He knows power......
