360 head mild port question

@318willrun
This is concerning the heads I have. 4343475A going 360 head going on a 360
I watched your 3 part you tube on mild home porting. 1 question for now. You mentioned intake gasket matching to the 318 intake gasket, not the 360 gasket. Is there a dedicated 318 gasket to use as a template. or did I misconstrue. Thanks as always FABO
