Ported TFS FE Heads......

[blykins]

Trick Flow is in a national shortage for FE heads right now, but when they come back in stock I will be offering them ported.   

In stock form, they will flow about 330 cfm @ .600" and start to back up after that, with a 220 cfm exhaust port. 

In ported form, they flow 348 @ .600" and go up to 358 cfm @ .750".  Exhaust ports flow 225-228.

As measured, intake port volume has went up 5cc.  Instead of a 175cc port, they are now right at 180cc. 

I will have a set on a 496 here soon.  Look forward to seeing the results.

Brent, do you have approximate pricing on ported vs unported, fully assembled?  Thank you.

[blykins]

Sure, I'll put pricing in the venders' section.

Awesome, be interesting to see if the 235* hydro roller strokers like a little more flow.

are there plans for an all out port job with these heads? also is the porting only available to new head orders or can people send their heads in..

If I get an application where we can do a "max effort" port job on one, we may do that, but even in box stock form, they will support 700 hp easily. 

I can have existing heads ported.

A rough rule of thumb is 2 hp per cfm.  That will depend on how radical the rest of the engine is, but it's a good rough estimate.  A CJ head will flow about 250 cfm, unported with good valves.  A BBM head will go somewhere around 280-290 cfm, also unported.
