Mechanically, I think the L67 swap is a better bet than to top swap.
and can't see how cost is cheaper... Only benefit to top swap is because higher compression will afford a 5% bump on HP over L67 with same level mod's. But you gotta add in a tranny too as the non-HD will be suspect after the swap. So if you're looking for that extra .5 sec shaved time in the 1/4 go for it.
All just my opinion! But do as mentioned, research it and ask all who've done it both and see what they say, then make your own decision and go for it!
