^that. If you have all three of those, do an ls/vtec and then build that one up and turbo it. Then you'll be able to sell the LS head and gsr block for some good cash. And just throw that d16 in the garbage lol jp but I wouldn't ever go with a single cam over a dohc. Boosting the single cam would basically put you at where the dohc is at, maybe only a little bit faster which isn't worth it at all
