any insight on what valve covers that fit the trick flow big block heads best sure would be helpful, i had planned on running the 440 source made in america fabbed covers but they have gone away because of covid for some unknown reason, does not matter if they are cast or fabbed, just want some that fit, i would be good with the trick flow covers ifn only they didnt have the "trick flow" script on them, i thought about getting a set of those and milling that off as a last resort.
