It’s pork and talk, I can’t make them rhyme even with a Boston accent ( which could do “car park” and “talk”).

In my London accent “park” and “talk” do not rhyme completely. Park has the usual “ah” vowel, but talk has an “o” vowel (in southern England we would call this an “or” vowel but I suspect that might confuse you more).
