Dear Sir,
I think those values cannot be more clear than they are in this table. Moreover, none of our ??competitors? will provide so many data. The profiles are fully symmetric, so you can easily calculate the valve opening and closing points. The optimum valve timing centreline should be found on the engine dyno and depends on other engine modifications, so for optimum result, you need adjustable pulleys. If you use stock pulleys, the valve timing centerline should be the same as OEM centerline. Please do not compare data measured on 0.1mm (like your OEM specs) valve lift as they are worthless due to measurement errors. The table gives the different profiles that are available, so you can mix them as you like. On the other hand, you should keep in mind that the two different profiles for the two intake valves do not correspond with the two intake runners. The two valves work the same over the complete rpm range, the long runner only work at low rpm, the shorter one at high rpm (shifting point will probably be around 4000rpm). If you want good performance cams, it is the best to have two identical profiles on intake and two (other) identical profiles on exhaust. The cams are solid steel billet. The information is not yet on our website, it will be on our new website which should be released in September.

So figure it out.
