hemi -itis,same heads as mine,has total flow on them,after i look them up,says dart made them,thats what i have,but on my header flange can only get 4 bolts to line up in them,im sure its a old fuel heads,they work though ,there not like the 433 heads
I was able to port the large header flange to make them work.The exaust port only uses half of the port on the flanges.They also showed a little daylight on the top of the port flang requiring adding some material on the exterior top of the tube to flange. Not sure if it effects my performance but I have to work with what I have. As much as I would like a new set of headers it's just not in the very limited budget.
I do have an issue getting the flanges to seal well on the heads.
