Blue Thunder Heads raised Exhaust Ports

[82ACAUTOCRAFT]

I am looking for feedback regarding Blue Thunder heads and their raised exhaust ports. I know the heads are great! Does the fact the exhaust ports are a 1/4" higher than normal generate much problem on installation with original manifold or headers. I don't feel like modifying my under car exhaust again since it is new, nice and ceramic coated. Experience appreciated. Thanks

My Blue Thunder heads were .400 higher and yes, we had to make extensive exhaust system modifications to get them in the car. In fact #5 and #8 did not fit and I am having them redone today.
