Direct Connection ( Mullen LA ) heads

Garrett Ellison said
I would start out with those and optimize the rest of the package. I would worry about upgrading the heads until after that “ONLY IF THE NEED ARISES”. The rules cap the class with ballast addition at around the 6.90 mark. It would think they would still be adequate for that with 12.5-13:1 and 3070 pounds race weight.

They'll work fine im sure, 400's hp

Here is a thread of mine from long ago, with 1.88 and then 1.94 intake valves and numbers from them.

The numbers
.100-63.8
.200-128.2
.300-190.5
.400-229
.500-241.5
.550-241
.600-240.1

So it saturated some , but is not really backing up, and it picked up a good amount from .100-.500
Sorry I lagged on the update, I'm really busy

The ex numbers after just mild bowl ,ssr , roof n guide blending...I also laid the floors casting bump back.
.200-103-80%
.300-146-76.6%
.400-169-73%
.500-180-74%
.600-192-79.6%

They were just for a hotrod, 35 plym and have about half the work done to them than the TA heads and the mullen heads in this thread.
I'm not implying I'm better than Bob Mullen or anyone else ..just pointing out its knowing where to work
..and i think the sm #s are off.
