Stan, I'm inclined to agree that I've got 043 heads. Based on the chart you linked, it looks like the only Mexican casting was the 043. Someone took the time to machine off additional identifiers so they may have been lightly touched up. Great info!

I just measured the rockers and they are 1.25 ratio (35 mm and 28 mm centers perpendicular to center of shaft). The ignition system is a Speeduino ECU driving a 2000 Golf 2.0L ignition module in a wasted spark setup...
Well alrighty then! I hereby retract everything in my post after the first sentence.
Ed, based on Al's info about the 1.1:1 rockers having the two lines and additional measurements I did this morning, I withdraw my speculation that they are 1.25:1.
Looks like a lightly tuned 1776 with 043 heads. Good enough for island puttering. I've had fire belching, tire shredding beasts and don't want the worry and expense that comes with them. Too many island visitors biking around each corner or staring at the sights to go too fast.
Thanks to all of you guys for your advice. On this Thanksgiving I am truly grateful for your guidance and encouragement!
