Push Your Twin-Cam out to 95 Cubic Inches

Now it’s time to get down to business. Tom recommends marking the rocker boxes (Photo 5) because, even though they’re interchangeable, it’s best to re-install them on the heads they’ve run on.

The rocker covers are now removed, and we’re ready to pull off the rocker arms. Always pull the breather bolts out first (Photo 6), this is VERY important.

These bolts extend into the heads, and, if taken out last, will strip the bolt holes in the heads. The rocker stand bolts are now removed, along with the rocker assembly, and we’re left with the lower rocker boxes (Photo 7).

Pop the rest of the lower box bolts and the head bolts are exposed (Photo 8). The four head bolts on each head come out and the heads can be laid on the bench.
