2.5V6 camlocks for GTA cams????

Don't know if it's discussed before, but i'm about to get set of GTA cams for my 156 2.5 and having in mind differences in cams, can locks for 2.5 be used for GTA cams.
And where the difference comes - it it possible to remould my 2.5 locks to GTA's somehow(applying it to the cam, and removing unwanted metal for example)
150 pounds for set of locks will be too much for me.
Thanks.

Totally Alfa do camlocks for the 3.2 V6 3.2 Camblocks (1.870.849.000) :: TotallyAlfa as do EB Alfa, less than half the 150 you mention.

Re-shaping the 2.5 locks to fit the 3.2 cams would require very accurate machining in order to keep the timing right and it's a sort of chicken and egg deal - how would you get the timing right to start with, without camlocks.....

For the effort and risk involved, I'd spend the 60 for some 3.2 locks. Sell the 2.5 locks to cover the swap maybe??

You can set the timing with degree wheel and a dial gauge.
That's how i did mine with regrinded cams.

I had to do this on the bike last week, it is a complicated but very enjoyable process

**edit** 6 weeks ago I didn't know what 106/ 106 cam timing meant

Best thing about dialling in the cams is it makes you realise just how important it is to get the position right - the smallest error makes a big difference.

For a stock motor, I think having the camlocks is an excellent tool - so easy to use and get it right.

Yep for stock motor that's true.
But maybe it would be good to try different timing on stock engine. 3.0 has 109 for both cams, maybe moving to 108 would give some hi end power etc....
