Direct Connection ( Mullen LA ) heads

Not the Mullen offset pushrod heads. The Mullen TA heads that were the fore runner of these heads.

Not to harp on it...... but how would a “TA” head not have the offset pushrod holes?
That’s literally what makes a TA head......a TA head.

So, if they didn’t have the offset pushrod holes...... then it’s not a TA head.

Edit- looked at that post and the old flow charts.
They call it a TA head....... so I assume it’s an actual TA head.
The thing I found the most interesting was that even the “Pro stock” level of work had the flow nosing over at the high lifts.

Here are the converted numbers for 28” at peak flow from that chart:
- stock head = 205
- bowl blend/valve job = 251
- normal full port = 269
- pro stock porting/2.08 valve = 296


One thing I thought was funny....... look how much space that flow bench takes up!!
That massive thing for only a 3” test pressure.

The flow test for the Chevy head seems a little biased though.
The converted flow for the ported Chevy head is 229cfm.
It’s not that hard to get another 10-20 out of them.
