Russ - that is an oversight on my part. I should have mentioned if anyone is interested in getting separate parts, to contact me via e-mail, scott@futurattraction.com. I can separate stuff out, though I don't customarily have it packaged that way. I've got the pro stock engine, but I've also worked on developing basically a Boss 351 with the finned valve covers, stock heads, single-4V intake and stuff of that nature. It's not 100% "there" yet, but builders are welcome to contact me. Sorry for not being clearer about that. I sort of fired off a reply without thinking my response through like I should have... Scott
