Response to Fel Pro 1240 2V gasket on Trick Flow intake

The ports on 4V heads are on 4.38" centerline distances. 2V are not and are biased of these centers.

The TFS intake has the runners/port windows in the 2V position. The port windows also apepar a little bigger than 2V stockers, perhaps to match the TFS heads. If you look close, the port windows appear to be cast off center in the scalloped feature of the flange. This is in fact what you need to do if you want to make it 2V position as cast but able to be ported to 4V. I wonder if one wall is cast thick than the other as well?

In any case, it appears TFS may have made good on the request to make it adapatable to 4V.

Best,
K
