GT40P and FelPro 1250

[nito88stang]

I bought my P heads and supposedly they were stock and only rebuilt. Well I got my P heads CC'd and they are 55cc in all chambers. So they were milled. NOw that I matched them to the felpro 1250's they match them perfectly.

P Heads With FelPro 1250

Typhoon against 1250

Typhoon closer

My question is, does it look like they were ported or do P heads normally fit this gasket so closely? I also included a pic of the gasket matching to the Typhoon intake i will be using. Will i gain much if i port match or is it ok if i leave the intake a little smaller than the head (since i'm so damn lazy )?

Thx

Mine matched the 1250 on the top and 2 sides but not quite at the bottom, looks like your splitting the difference in the pic, you should be able to tell if someone gasket matched, you probably have the stock size ports

I also have a set gt40-p heads and when i got them they were not ported and were almost to the 1250 gasket.I did alittle touch up on the ports but haven't driven the car yet.
