If I were attempting 11’s with the 3.55’s......I’d buy a 408 rotating assy before I bought aluminum heads(being in the position 318will is in, with a few sets of heads already in his possession).
Then I could also get by with a less expensive converter and a milder cam too.

I alluded to the stroker but of course I didn't say it because I know he would have wanted to Tar and feather me for even mentioning it.. but you're a guru out here and you can get away with saying something like that and just getting a polite thank you for the effort..
