Hey Jason...I am no expert on x-rams...I'm just comparing your pics to other original units...I have an NOS xram top plate...It is dated exactly the same day as yours!!!

I also have a used lid that is dated one day prior to yours...Upon reviewing my xrams, it seems that the intake lids that are dated in this time frame, have the date stamped in this same area...atleast on the day of your intake and one day prior.I have 2 intakes whose lids are both dated one day apart in Dec. 68...and the dates are on the other side of the underneath of the intake...opposite the vacum hole...and the repro that I purchased for comparison is dated one day prior to yours(just like my other original), but the date code is actually in the wrong spot...it is locted same as the 68 dated intakes...Wow...Did you get all that?

Anyway, your date is very similar to mine..I will try to post a pic...

As for the machined surfaces...the repro I have seems to have small swirl marks where it was machined with a small type bit..or cnc machine? All the origionals have more smooth surfaces and barely any visible lines...on the edge of the top...If you look more on the side just below the carb flange...the originals all seem to have been grinded or finished off abit with some sort of a machine that maade vertical lines...these lines continue around much of the edges of the top of the originals...kind of like they were trimming off the extra flash after the mold...The repro I have has no marks whatsoever....i hope that helps...if you can post a pic of the edge just below the carb flange, ill tell you what I think...and Ill try to post some pics soon too...for comparison s sake...

But do remember...I have not seen one of heartbeats intakes...the repro I have is from the other guy......Does anyone have any pics of the date code on the Heartbeat unit to compare??
