Has anybody tried out the dart heads yet?I've been looking but every head comparison I've seen so far hasn't included them. I just went through the car and changed everything but the stock 98 heads. If there is s thread point me there I will follow.

I am using the 225s on my car as-cast. I had ETP ported 98 heads last year and I wanted to get away from the 'notch' on the bottom so I could use MLS gaskets so I sold them and picked up a set of 225 darts from W2W.

First time out this year I beat last years best by a tenth and 1mph in the 1/8 at a higher DA, same track, so thats all the comparison I can give. I also lowered the compression ~half a point also so I'm happy so far with them. The ETP 98 heads flowed pretty well in their day but they were on stock valves.

All I did was take them out of the box, blow them off and bolt them on..
