Trick flow 325 power port heads?

I just noticed these today, are basically a worked over version of the 290's?

Sure is, It's trick flows cnc version if I remember correct.

Ah. Summits selling them for 1130 something bare made me raise an eyebrow...

I think Lem has P-51's complete for $2200 or $2400. Will flow better.

I've been giving those thoughts. I'm not In need of a complete set as I do have cam, springs, several sets of different size valves. And I've still got my ported Iorn heads. If these heads are standard valve placement then they could work with my current pistons

No they are not... you can fly cut your pistons

Yea I knew the p51 wasn't. But the trick flows might be. Now I'm thinking about scrapping my iOrn heads again

The TFS Street heads are Standard valve Layout.

Anyone have flow numbers for these heads?

they are posted on the TFS website.

I found the 290 heads flow numbers but not the 325's I'm lost

i looked at them at PRI....visually looked great. It looks like the full-on CNC work would probably be pretty good out of the box....but would save a good porter a lot of time to make a killer set of A heads. i am looking at them....in more detail...in a few more weeks...for a possible upgrade, bringing 18 bolt heads to the 605 and stepping my 10 bolters to the 514, replacing the Blue Thunders.

I'm giving them serious thought as well, better than my ported iorn C9VE heads

Does anyone have updated information on these heads? What type of flow are they capable of?

Just found this on the web. http://www.totalengineairflow.com/products-page/products/cnc-ported-cylinder-heads/trick-flow-325cc-429460-cylinder-heads/
Flow numbers are at the bottom. I know the intake numbers are not bad, but am I correct in thinking the exhaust numbers are much better than iron cj's can produce?

Factory iron CJ exhaust ports are pitiful.

Agreed, the intakes on my max effort D0Oe-R's are much better, but the exhaust is still not as good as the 325's, so I am wondering if these are a good upgrade. What power level are these capable of supporting as is? Also these heads have the stock valve location so the pistons I have now should work without cutting new eyebrows right?

and they still make power..... Imagine that !?!?!

I was interested in those last year because they had 80 cc chambers.
