408 cam / build help.

I think X heads may flow a bit better stock but if they are going to be touched up, J heads would yield essentially the same flow after working them both over. You should be able to find 2.02" J heads for half of what X heads go for. If you are saving for a set of Edelbrock or TrickFlow there is no sense in dumping a bunch of money freshening up old iron outside of what you can do yourselft. Find a set that will get you by as is or run what you got.

I've got a new in box example of that XE275HL cam with lifters that I hoped to get installed when the car is down for the winter. I might want to try a solid lifter version so if you are interested, shoot me a pm.
