Another 87 octane/aluminum heads question

Ramchargers are awesome, had one for a decade. Never let me down.

You haven’t complained about power needs. Why tear a young engine open? I’d suggest you leave the top end shut until you start seeing signs of problems where you need to change the heads.

Instead, work on the new fuel injection. There are many brands and styles. It’s going to take some time to tune.

The tune is going to dictate if you’re going to have problems with the your new heads anyways, if you run lean and try to move that heavy truck with a lot of throttle, you will detonate. If you run on a razors edge of higher compression and combine with low octane, the tune and timing need to be precise.

There are a lot of fuel injection systems out there now. I run megasquirt, and I can tune fuel and ignition timing on-the-fly.
