Before I start, no, I did not do any research on this topic as Im assuming such a strange question does not come up very often.
My question is this- how hard is it to port GT40 heads, and make them flow worse...not better?
The reason I ask- I picked up a set of gt40 (not P) heads for 50 bucks. I ported them pretty thoroughly, no polishing. I took down the valve guides the best I could, and opened up the bowls quite a bit as well. I stayed away from the floor for the most part, cleaned them up a bit thats all. Cleaned up the intake side as well, taking the guides down. My question is this, I hear alot of talk about opening up the bowls etc.... can you make them worse? Just curious, I trust my work but again Im no expert...
