20V: 20v gze

[rspidydude]

Ok i have a bit of a problem, for about a week my gze has been tickin and it has gotten worse over the past week. I was thinkin about doin a 20v swap since it is almost a straight drop in. but i need to know what u guys would recomend as far as going for the st or the bt. i was also wanting a little more power out of it seeing as how i already have a few things on my gze, i was wondering if i would be able to put the s/c, intake and manifold on the 20v. now i know that they have the same blocks, im just wondering if i should put in the gze internals to lower the compression. any input u guys have on this idea would be great, and if no one has tried it before i would have no problem doin it my self just to see what happens.
