#19s or #24s

24's and keep the mods coming
or keep the 19's if you are done

I would go with 24s just to be on the "safer" side.

Long tubes will be fine if you already have them. They're worth a couple hp.

As for the injectors. You could get by with 19#'s, but you're getting close to needing the 24#'s. So if you have to buy them anyway, go with the 24#'s and the appropriate MAF meter for the 24#'s.

I have a similar combo. Same cam, 1.72:1 rockers, stock heads, stock intake and throttle body though. I run 24#'s becasue I was planning to put heads and an intake w/throttle body on it at some point. Now I'm going to sell the car I think. Anyway if you have to buy new injectors, go 24#'s.

yeah 24#
