Reeves1,
Yes, port flange surface angle is the same on the Canfields as OE iron heads.
You can see that if the Hookers end up, for example, 1/8 inch from the floor
with iron heads, which happens with Hookers on other cars, then it would be
a problem raising them up half an inch. I had hoped that someone on here
had already crossed that bridge, OE heads with Hookers that is.
Thank you.
