120/104 cams is my other option.
So I took your advice and I put the 120/104 cam into the simulator and its a nicer wider/flatter torque curve. The HP curve looks actually a bit higher and also flatter.
Looks like the 120/104 cam is going in! Also solves my piston / valve clearance issue.
I'll save the 171e for when I get some higher compression pistons!
Thanks Steve again I appreciate your feedback.
The ports on the heads have been opened up to 40mm from the stock 39 Intake and 35 exaust. Any comments on the affect of the opened ports on this configuration

I think you'll be much happier with those cams,....
Its not difficult to negatively affect head flow with simple enlargement of the ports and I'd offer that these stock heads support up to 330HP in a 3.0 to 3.2 litre engine without touching the ports.
Caveat Emptor on making any changes without being able to check them on a flowbench.
