Installing Cams, What's NEEDED??

[vtecbrad]

I am finally going to get the Cams installed into my humble little car.
My question is this what else is needed when installing Cams??
So far i have bought: Crower Stage 2 Cams, Crower Dual Valve Springs, Crower Titanium Retainers, Ferrea Valves, Adj UR Cam Gears, Timing Belt Kit.
I Am purchasing: Ferrea Manganese Bronze Valve Guides, Ferrea Valve Stem Seals, Ferrea Steel Valve Locks, Cometic Head Gasket, Skunk 2 Cam Seal.
Please if anyone can think of anything else that is required for the install let me know. Port Job May Be Done, NOT SURE YET!!!
Now the ECU i am still thinking about, should i go Hondata or Microtech, please explain why you would choose?
Anybody got any ideas on how much it will cost all up including a full head clean service??
anyone done these mods if so what were the power gains like??
Also if you have done it who did the work for you, (Sydney Area)
Thanks heaps guys & girls.
