What the difference? Any advantages/ disadvantages?

None at all... give them a call. Ive got wade 818 regrind in my car. The only difference is that youve gotta machine the lifter blocks to suit the smaller profile of the cam due to the regrind. SO if you ever run another off the shelf cam youll have to get a a stock set of lifter blocks to replace your machined ones or get another regrind You can send them all to them in a package and have the lifters done like i did, still works out to be cheaper then a off the shelf 818

Ive already dropped off my cam and lifter blocks! I was just curious cause someone said that i should have just gone and bought a new camshaft just got abit worried! Did you notice a good difference in torque? Run ok on standard computer?

Yeah i had it running on 3TA brown tops fine... cant comment on power difference because it all went in at once. One of my mates put in a TX1 which is a very similar profile and it made a notable power difference with just 3ta/browntops

When I spoke to wade about the difference the only thing they said was the price

Ok k cool thanks Wil yous happend to know the order of the rockers? When i was cleaning them i messed up where each set goes?

Heres my package that i got... youll need double valve springs aswell Some original photos have not been recovered yet.

I just ordered a regrind, machined housings and springs cheaper than a new billet!
