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.

Need Time Sert installation tool to convert P90A hydraulic lifters to mechanical. The job requires threaded inserts (easy and inexpensive) using a special tool only available in a complete kit including bit, countersink, tap & installation tool (one-time use and very expensive - $200+). I only need the installation tool. Size M18 1.5 but with special threading at tip. Anyone have the kit or individual tool for sale, rent or ??? I'm trustworthy. Rob in Arizona
