Thanks guys.

Yeah I've been keeping my eyes on your Sierra Zetec topic, interesting stuff. I'm still not 100% sure how much stuff I'll end up fabricating myself, retro-ford catalogue of course is a very tempting one.

I agree about the blacktop versus silver top too. Black top will have solid lifters out of the factory, so it's probably my preferred option. OFC it's possible to fit solid lifters on silver top too, but I'm probably gonna start hunting black tops.
