I'm assuming the 418 was with a locked converter? BTW, congrats on the times that is really amazing for box stock heads. 94mph in the 1/8, the car is moving out for sure.

Of all the CNC'd 21deg heads we've sold, I don't know that any have finished sorting out their builds to the extent that they've begun to run on track and work on getting the car sorted out. Even then, that is likely only a few guys since most will never go run the car beyond dyno testing. They certainly have the potential to be made into something worth running over a well done stock casting.

I've got an out of the box set on a 355ci with all the air a T trim can provide.
I've been fighting the car the last few months and put away for the winter.
Should be fun when it is sorted out.
For being sold out and hard to get there doesn't seem to be many that have them on here.

Would a set of these ported from you guys would be too much head for a typical 350/355 setup? I'm sure these would be killer on a 383/396.

In your honest experience/opinion, how is the geometry on those heads?

They dont really compare to AFR 210s... They are 180cc heads you're comparing to 210 cc heads, and a 21deg head vs a 23deg.

2 completely different heads you're trying to compare.

It all depends on the combo you're talking about...
