New Head comparison for you
New Head comparison for you Rich @ Fairfield and Advanced Dyno have teamed up to run some testing on a new Head program that we have had in the works.
Rich has run 3 sets of heads on his car and we pulled the head that we have felt made the best performance and put them into a test with My car.
We ran 3 sets of heads on my car as well
The first head is the Lingenfelter 243 which netted 486 rwp.
The Second Set are Trickflow 225 @ 12.0:1 Compression whick netted 501 rwp
The third set is Our custom GM Performance 243 head whick netted 504rwp.
I am posting the results between the Trickflow heads and the GmPerformance heads that we have been working on.
Trickflow 225 run is in Blue
Our 243 is in Red
As you can see the 243 Heads that we have been puting together are putting down some very respectable numbers. We have a package here that makes 504 RWP with a 243 Casting head.
I have made 507rwp with the trickflows months ago but could not reproduce that anymore as it is hotter out so we made pulls with tuning right before the swap.

That's a nice looking 6.0L graph! Well done!

The TFS heads will make the power with pratically no hand finish work, it is very difficult to get a 243 head to repeat without hand finish work, and then the hand finish work becomes a inconsistency in power production.
Good luck with your new head program Robert
