283 heads

NHRA/IHRA list two casting numbers for 283 heads. Which one is better to start with for super stock the 520 or the 896? I have 3 sets of the 896's. Thanks

Same thing I have been told by the 283 Pros....

896's for Super Stock, because they will be ported anyway..

520T's for Stock, because they flow better in stock form...
