Question about Holley jets...

[jtybt]

I was going thru my loose holley jets and found a set of 61'H' and 67 'H'.

In the holley book, I didn't find anything with an 'H' suffix or designation.

Anybody know what it means or any specific purpose for those jets?

I've seen that on some from time to time, don't know what it means. Have only seen it though on jets that came out of a carb, and only newer stuff at that, never on any packaged ones.

Call Holley, they will tell you.
