360 LA installing Promaxx Aluminum heads
Finally got the top end off my 360 and am preparing to install the Promaxx heads that I've been lugging around for over a year.
I'm sure more questions will come up but first out of the gate is spark plugs. I've been using E3's (E3.46) which has 13/16 hex, .750 reach. The 13/16 hex is not going to fly with the new head. Can anyone confirm the E3.58 is a suitable replacement? It's 5/8 hex, .750 reach. Insulator is slightly shorter. No clearance issues at all with my TTI shorty's.
