im in the same boat. If I had a stock SOHC now, it would be different. I'd put the couple hundred into a hybrid. But i already have a pretty stout SOHC. When everything's said and done with it, it should be in the 12s solid at least. I dont have much interest in making the car run quicker than that.. (now), so why create a custom engine install to go the same speed. I dunno, i'll stay SOHC for now especially since i have other projects to finish first. But I still have this Avenger head here for future projects.
