i talked to simons cantact in japan. this is what he replied with.
"" Thank you for e-mail
I checked price
16x # Valve spring:14750-NL6-700 = 1,980 yen
16x # Retainer : 14771-NL6-000 = 1,980 yen ""
so 1980 yen = 17.99$
I am assuming those prices are for each spring and each retainer.
so it looks like it comes out to about 288$ dont know about
the shipping
You would only need 8x retainers and 8x springs as the spring is sold as an inner/outer assembly. I dont know about the part # you have for the springs above, see my post just above. The -700 is almost 3 times the cost and I cant find any info for the -700, only the -000. The 14750-NL6-000 is what is shown in the HRC SP1 Manual as well.
Here is a photo of the HRC SP1 parts I have received in the past.
Well, I got off the phone with Rick Hobbs and Brian Ucheata (sp?) today. Brian is an American Honda road racing guy but mostly dealt with the works parts not the kit parts. Rick built many SP1's with kit parts and had some memory of what he found out, here is what they remember. Brian says he has never seen any HRC valve seats that where Ti, they have all been steel. Rick seems to recall the HRC SP1 seats where thinner to allow more valve lift with out the springs going in to bind. Rick said from what he remembers you could not run the HRC cams with the HRC springs and retainers with out the HRC seats with out binding issues. With the lift of Dales cams there is no problem with spring binding with the OEM seats. Rick could not tell me for cretin but he believes the inner seat may have a slightly different diameter to fit the inner spring better and prevent the spring form walking around and causing wear to the seat or spring. As I said, Rick is going off his memory and the only way to be 100% is to install and measure for yourself. I have a set of HRC seats ordered so I will be able to compare them to the OEM seats soon.
It gets a lot more complicated but to sum up our discussion...
-The HRC springs have less installed seat pressure then OEM and require less valve mass to prevent float. The Aluminum HRC Retainers help a lot.
-The OEM springs will go in to bind with any more lift then the OEM cams.
-You must use the HRC retainers with the HRC springs and if you run in to binding issues with the OEM seats you will need the HRC seats.
-The HRC cams require the HRC seats to prevent spring binding.
-You may be able to get away with the OEM seats but it would be wise to check for wear on the seats after 100 miles of hard running or so.
-If you dont have the Ti valves it would actually be better to run the OEM (thicker) seats as long as there are no binding issues to help add spring pressure and prevent valve float. This is especial true with a rev limiter above OEM.
There, I hope that all makes sense.
Neither had any info on the -700 spring part number but both guys said stick with the -000.
I am still waiting on one or two other sources that may be able to back this up (I love redundancy).
As I mentioned before, don't worry about Seats.
I've got them here, at least for 10 Engines they should last.
And- you need the black marked springs .
The Yellow marked Springs do work only in conjunction with Ti Valves.
I have made ~ 18 Engines with that Setup:
Black marked HRC Springs
HRC Retainers
My Seats
Works perfect

Which ones are black and which ones are yellow? Is that the difference between the -000 and -700 springs?
Directly on the Springs.
Simple black paint on them.
Approx 10x10mm Area where they're marked with the paint.
On the Pic from Damom you're able to detect the black mark, upper right hand spring right side, 2nd and third windup
The HRC inner spring seat is the same thickness but has a 17mm OD (15mm for OEM) for the inner HRC spring. The HRC outer spring seat is the same as the OEM but has been ground from 1.52mm to 1.24mm thick. The thinner outer seat was to help with coil bind issues with high lift HRC cams. Both parts are steel.
SP2 Kit Springs are also yellow marked.

My Cams have been unavailable here for 1.5 years, but now it seems they are available again.
But the Pricing ist hard ~ 1700 Euros( without VAT )
So I think Josh will be able to offer a way better pricing, and as far as I know the first Set of Prototypes ( to check manufacturing Quality) he will receive in 4 Weeks, direct Copy of my Cams.
The Specs:
Duration Intake/Lift: 270° / 12,35 mm
Duration Outlet/Lift: 264° / 11,90 mm
1700 euro = 2415 dollars + %20 VAT = 2800 dollars total
thorsten did you run the hrc seats with your cams also?
No - I did run my own seats, made from Cro-Mo steel.
The preload start,middle and endpressure aswell as max lift spring "on block" clearance was calculated from a buddy of mine, and they're perfect.
Half the costs of HRC, and I still have a couple of those seats.
I have had quite a bit of interest in these cams of late ,so am getting another batch made,probably another 6 sets,of which 3 are spoken for.
The price is US$1350, less than the last batch due to the sudden drop in the value of our dollar, so now is a great time to get a set.
Theres no telling how long our NZ dollar will be as low as it is,having dropped from US$0.80 to US$0.53.
Feel free to pm me or email any questions.

Ran into a few issues which affected the time it took to get them finished, however they are all done.
I still have a couple of sets left unspoken for.As the kiwi has strengthened back against the $US,I've had to adjust the price and the remaining sets will be US$1450 incl postage.
