Little bit of a rant about Mopar heads...

I have found the 1.88 heads to have more port volume than the 2.02 heads, I believe the tulip valve is to blame...the 2.02 has a huge tulip 'it's a heavy valve too' lol plus they dont do a real good throat cut, so it's basically a bigger seat and thats it + a now bigger tuliped valve eating up the bowl area.

But when I cc'd I found 155cc for 2.02 J's vs 160cc for 1.88 J's ...interesting, ya know...I think it was a 72 demon that last had the g stock record...before it ran out
the numbers are like 1.88=200'ish cfm vs 2.02=220'ish cfm

I need to do my own testing on the 1.88 version since I have only personal played with the 2.02 heads and came to this finding, but back when I had to pay people to flow them those are the 1.88 numbers that were recorded -technically 189 @ 25'' depression converted to 28''=200
