I don't thinks that's possible, you refuse to see the value in them and after all they are just cylinder heads, they are not magic. I think that's the problem is a bunch of guys still think there is some magic wand. Not taking into account the quality of parts,machining and improved rocker location these will not perform much different then a very well ported set of rpms or sms,but unless you know how to port then you will be well over the price of the trickflows and that's not including the upgrades already mentioned and/or any machining that needs to take place.
