heads

what degree are the older 350 heads?

23 degrees?

all factory 350 heads are 23 degrees...you have to buy aftermarket to get anything else...they do flow a lot more but also cost about 4 times the amount and most of the timw you have to get new valve train and even have a set of custom made headers unless it is in a draster or you have a ton of room...my dad had a set of 14 degree heads and he paid 4000.00 for them ....
