SOLID LIFTER VALVE TRAIN 944S / 944S2 / 968 / 928 16vLifters are being built dimensionaly so that you can remove your factory hydraulic lifter and install our solid lifter with lash cap. This assumes your valve height is per Porsche specs which is 44.4mm/1.748" Intake and 43.4mm/1.708" Exhaust and your camshaft base circle is like that of a stock camshaft. If your grinding custom cams, you may need to adjust your valve tip height accordingly.We are building a separate intake lifter and exhaust lifter. So if you're building a head in the mean time, willing to wait for delivery on our solids set-up, and want to know what to tip the valves, go with the stock height values which are the same for the 944S, 944S2, 968 and 928 16v heads. |
