Stock 289 through windsor heads are designed for high flow velocities, not high flow volume. Considering, the original engines were relatively small displacement, long rod engines, this made good sense from a low end tourqe output, on a stock level motor, perspective. If mid-range tourqe and horsepower production are the the goals, then the flow volume needs to be much higher, and will really wake these motors up.
no i meant rollar lifters, cause i know the head has to be a certain way in order to use them but i didnt' know if they used rollar lifters with all the engines that came with E7 heads
