Hello all I'm putting together a 408 stroker on a 360 La block. Wanted to use trickflow heads but they said the only rocker assembly to use was from Harland sharp and cost $800. Does anybody else have experience with the trickflow 190 heads using a different rocker or I am considering using an Edelbrock head 60779 as long as I don't have to use a super expensive rocker assembly can guys tell me what rockers theyve used with the Edelbrock or the trickflow 190 thanks Mike
