The reason I would like to get ported heads is because I would not have to do it later on. Also, the more the heads and intake flow, the less boost I would have to put through the motor. Less boost equals less fuel and less problems. The main reason is because of my Holley intake. The lower has a terrible port mismatch. My Darts' I have now are matched to a 1250 gasket and the Holley lower is unported. The bottom and side walls of the intake ports of the Holley meet the heads perfectly, but the top port wall of the Holley is about 1/8" taller than that of the 1250 intake gasket dimensions. This leaves a flow hinderance that I would not like to have in my intake tract with my TT setup. All TFS TW heads are box stock to a 1250 intake gasket and I would have the same problem with them. I am looking for a set of heads that are ported out to a 1262 gasket and then I will have the lower intake matched and milled to line up with the heads. If I didn't have the problem with the lower intake mismatch, I would most definitely get box stock TW's but I don't want intake port turbulence.
