OK, Jef, I'll jump in. I really like the SE 204, and I am currently running a 204 with 95", SE 16 guage pipes and SE Heads. The exhaust note is low and the cam has a very nice mild lope. Don't know what couching is. If I had to go again, I would go with gear drives.
Higher compression is good, and it adds power at midrange. 9.7 seems ideal with you heads and cams, Oil cooler is great and should be added.
