K4 Camshaft Question

[hadal]

I have a pair of camshafts I hope to use in my ZR hillclimb car, although new I believe they were intended for the MG XPower 1.8 185ps engines designed for the 2003 MG ZR one make series.

There only markings apart from the Powertrain/rover camshaft blank part numbers is MGXP902, from the measurements I can make they appear to have approximatly 10mm of lift and a 280 Degree duration?

Does anyone out there have any more details on these?

For those who dont frequent the MG section, they are the Piper 872 profile as used in the VHPD engine, they require solid followers, have follower gaps of 8/10 thou and should be timed at 120 thou/100 thou lift at TDC. The valve acceleration is not too aggressive so they will hap[piley work with hydraulic followers converted to solid. They give similar characteristics to the Piper BP285H profiles.
