New Powerport 325 TFS heads? CNC!

Someone asked about them quite awhile ago but to my knowledge noone has any hard info on them yet. Maybe I should of sprung for this version versus the 290's but didn't want to rage uncharted waters. I would bet they are good heads judging by the quality of everything I have seen from them. I would like to see some flow numbers and a direct comparison between them and the 290's with some dyno numbers.

yeah a that would be good to see the gains between the two

TFS 325

I actually emailed them a couple weeks ago and the reply was that they would be available in the next couple months. The CNC flow rates quoted were on the order of the Kasse P51's. Don't hold your breath on the availability though as many new products take time to be released and demand also.

FWIW Mark

Mark they are listed in the newest Summit catalog. That would be great if they flow comparable to the P-51's with standard valve layout. They are listed as $2699/pair through Summit and only offered assembled right now in one configuration.

witch a little more pricey than the p51s!

I just looked at Summit website and the last sentence in the description says bare heads are available.

What is the good price on a set of P 51's ?

Gary :-D

I believe about 2400 the new Powerport 325 are 2700 but if a guy wanted to make a big step up from an engine with standard valve layout pistons in and cast iron heads these would be the right choice assuming that there is adequite p/v clearance.

I didn't look online just at the catalog but I would imagine the TI retainers are a good portion of the price difference between the 290' and the 325's.

Those 325 heads from TFS are CJ intake port size at the flange; the 290's are D0VE intake port size.
Look at ALL the valve lifts when comparing air flows ... not even close to P-51's in the mid-lifts.

I dont think there is a another bbf wedge head that keeps up in the midlifts to the P51.

my powerport 290's cam with tit retainers and 164 manley springs. $2,100

I was a little surprised to see they didn't bring any of the PowerPort 325 heads to the IMIS trade show in Indy last week. Was really looking forward to seeing some. Maybe they will have some at PRI???

LOL...
When I e-mail TFS in July I got the same response !

BTW guys, those 325 Powerports have 80 cc chambers.

The chamber is where some of the flow came from.

Can someone post the flow numbers?
