Brent - thanks for the message. That is why I was thinking of the Lunati ... as overall duration is not very long (268 intake and 276 exhaust) so I assume low down performance will be good, but the lift at 0.05 is much higher and more area under the curve, plus much more lift, so I assume I get HP gain?
Does that make sense logically?
Have emailed AFD as when I got the heads I got the "complete street" package and i want to check what springs were on there and therefore if they would work with the cam.
Need to find who in the UK would do porting work on the heads and intake. And at some stage probably examine by exhaust set up to see how optimal / sub optimal it is!
