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 :D

everything i have heard is that the stock p heads almost match the 1250 and that there is no need to take the slight difference out yet. i'll compare my NEW p's to the gasket tonight if i get a chance.....

Is the port difference from intake to head worth matching, or is the difference neglible and the gains minimal?

You will want to check the alignment of the intake to your heads installed.

Remember, if you match to your heads, it will only fit those heads on that block.

My preference for a stock/near stock app. is to leave it alone.

I'm w/ John. Leave it.

If you decide to work the intake a bit (looks like a little wouldn't hurt) be sure to tape the gasket or index it to the intake and then bolt it to the head on the bench to find where the gasket will align exactly. THEN mark/scribe your gasket line and stay a tad smaller than the head to ensure you don't overlap.
