Are the headers full length or shorties? What primary size?
The heads are rather small port- and valve-wise for 400 HP. Hate to disappoint you, but you're probably closer to 325.
No cat & no muffler???

Nah, I'd say 400hp, IF IF IF IF carb is tuned properly, has 1-3/4" tube headers and a real good ignition curve. more if ported heads. Those heads are not far from Edelbrock RPM heads, pretty much, which made 425hp+ w/same combo and less CR. (9.5:1)...
