5.9 Magnum Street Build - with dyno numbers

Yeh, EQ heads without guides are a pretty risky proposition.
I refreshed a set of used ones several years ago.
No stuck valves, but someone had reamed the guides so they had excessive clearance.
I put bronze liners in them.

Looking at the fuel flow disparity between A & B, it would appear a weaker secondary spring might yield a few extra ponies.
The secondaries don’t look to be open enough to contribute anything till after 4k.

Back to the dyno after the repair?
