I'm really in it for the tech, so things like bodykits and other stuffs are not really something I'd think about.The toda oil pump does not pump more oil. You can check the toda catalogue, and not in any way it claims pump more oil. It's made from better materials so TODA claims it lasts longer, but I seriously don't think that something that looks and is sized exactly like the stock oil pump can pump more oil. The trick for oil pressure is the bypass spring, and that's what people use.Valve grind doesn't actually mean grinding the valves in local Malaysian-speak. It means grinding the valves and valve seat together to ensure a good seal.Since you have very good compression, it's not a necessity, though with the head out, sometimes you have to think 'why not?'. Then again, compression is not dependent on valve seal alone, so perhaps your valves are still in very good condition (I'd leave that to your mechanic to check, maybe he may think that there's too much deposits, and the valve and seats should be ground?)Port work... well, this is a bit difficult. No one can really do it without a flowbench, because it's supposed to be an exact science of getting the four ports to flow exactly the same. Different head porters have different methods, and they all get results. I'd only trust hard numbers though, so if a port work doesn't include flow numbers, why bother? But good port flow can be ruined by poor exhaust/intake choices, so that's the hard part that I can't really put a finger on yet.Based on your part numbers, those are Spec C, not C2, as is apparent by the part num.Those numbers are advertised durations, in the order of : Primary lobe (pre-vtec) : Mid lobe (vtec) : secondary lobe (pre-vtec)Look at the Toda C cam sheets and you will see that the number I mentioned are Spec C's middle lobe (HI as TODA calls it) numbers at 1mm valve lift.Can you help me out and note the numbers in the cam papers?I'm looking for the Cam Top Centre number and the Degrees of the Spec C cams. They are in a box below the diagram of the cam phase.The opening and closing numbers I can obtain from those two numbers so I don't need those.Please post here when you can. I'm seemingly at loss at how to find Toda C cam sheets as no shops in Malaysia has it at the moment.Oh, and I forget, you're supposed to lock the middle lobe in place in order to measure clearance, your mech should be able to figure out how.</blockquote>
