Rob1972 Posted February 1, 2019 Share Posted February 1, 2019 Beginning buildup of my '72 240Z and a F54 / P90a with triple carbs...looking at notches for injectors and choices for manifold gaskets. I've seen lots of gaskets that follow the outline of the notches and another one that covers the notch. Seems to me that for better airflow I should block the notch with the full circle style gasket. Recommendations? Also wondering if some have welded the notches up and grind as necessary. Quote Link to comment Share on other sites More sharing options...
gnosez Posted February 13, 2019 Share Posted February 13, 2019 (edited) I can only tell you about my experiences with notched heats and triples carbs. I don't use a gasket and haven't for the past 10 years on both my street 240 and my race 240. Red RTV for the exhaust and Hondabond for the intake. The race engine comes apart each winter.
