At Dan Vance Racing we offer custom high performance cylinder head and engine modifications for Harley Davidson motorcyles. We have performance kits for every riding style. We can provide torque and horsepower increases in any or all RPM ranges.
Only $2095.00
Here is my best selling performance package now updated
for the 2008-2012 Big twin models.
You send me your parts & I will port the heads & bore the cylinders & ship them back to you with a new set of valves, a new piston kit, gasket kit, S&S pushrods/covers and
a set of cams from Andrews.
You
can also purchase these kits as an exchange. For an additional $500 ($350 heads,$150 cyls), I will send you a kit
with all components all ready to install including a set of my heads. After you have installed them, you send me your take-off
heads & cylinders & I will refund $400. For this option, the parts you return to me must be the same color
and condition that I have provided to you.
The combination of good flowing heads and the correct cam and
compression piston will get you all the power you want and in the rpm range you ride your bike. I have been riding Harleys
non stop since the mid 70's. I have owned and wrenched on just about every bike that Harley has made. I consider myself as
an average rider who enjoys riding two up through the hills and valleys of New England. I enjoy the feel of a throttle that
responds when I roll it on. I occasionally like the rush of 2nd, 3rd and 4th gear with the throttle at or near full throttle
but am not overly excited about going over 100mph.However, I do want to get to 100 as fast as possible, on occasion. I like
and want a throttle that responds when I twist it, not just make noise.
These high velocity heads will do just that. "INSTANT THROTTLE
RESPONSE". More air, faster air, better cylinder fill, bigger boom and power that you feel immediately when you turn
the throttle. With this riding style in mind, I have come up with a package that is perfect for everyday riding, good manners
in town and traffic, good gas mileage, makes good dyno numbers and will thrill you every time you ride whether on the back
road, highway or just carving corners with the guys. I am sure that, whether you own a FLH or a Dyna, you will also enjoy
this combination of parts. The cam will dictate where and when the power comes on. For touring bikes I really like the Andrews
26 or 37 gear drive cams and for the lighter bikes the 32, 54, or 55 cams work excellent. I have also had good success
with the Woods cams, like the # 6, 7, 8, and #9. These kits are not limited to these cams and will work great with all
cams. These are just the cams I use most often.
The heads have been reworked with bronze high performance valve guides and high tulip
1.900 intake valves, guides. I will adjust the spring pressure for any cam up to 550 lift, cams with higher lifts
I recommend new valve springs. The cylinders are bored and honed using torque plates and SE pistons with a choice of
9.3 or 10.5 compression. Or I can mill the head gasket surface for any compression you would like.
The kit includes a set of of my ported heads, cylinders bored
and honed to size, a set of late model chain drive cams (your choice of which cam, or I can give suggestions) a complete MLS
gasket kit, .(030 or .040" head gaskets) for putting everything together, and a set of S&S adjustable pushrods and
covers.
