What about Victor Jr. heads? they're cheaper than the AFR stuff, otherwise I'd go with the TFS R heads. CNC porting sure looks nice, but it aint all its cracked up to be on the AFR's.
Will Trick Flow Twisted Wedge heads work?

in the past on my car I have used AFR 225 heads - victor Jr's - twisted wedge and I now have Brodix Track 1 M2 heads..
If cost is an object then the victor jr's would probably be the best bang for the buck, I think Edelbrock states they flow 290 out of the box.. mine came in around 272 @ .700 but there is a lot of room to grow with these and I got mine for 1200 shipped to my door, the twisted wedge is going to cost you 1100 or so plus another 500-600 to get the extra 20-30 cfm out of them... the AFR225's out of the box flowed 326 with these on my 393 I made 510 @ the wheels at 7400 rpm and on a 250 shot made 748 at the wheels so I know they work as for the brodix heads they are very nice looking but to get them done right they are going to cost some cash... bare from M2 they were around 1700 plus I had FTI do more work and then put the valve's and springs in ... all together it would take about 3000 to replicate these, the only bad thing is my AFRs still outflow them by a couple cfm on the intake and exhaust... My AFRs had a special valve job done and a few other tricks at AFR since I was testing the new 225 for them....
The bottom line is you need to figure out how much you want to spend.... these heads are all good some need work some dont... if it were me the R heads would be out of the question becuase if you go that route with special pistons and headers I would just get the victor Sr heads, another head to grow with is def the Highport which makes a ton of power but needs different exhaust.... My 225's and brodix heads have both the standard and the wide bolt pattern for the exhaust while I think the Jr's and twisted wedge only have the standard pattern...

I don't know about anyone else, but I really enjoed this post.
Tons of first hand experience, thanks for sharing.
Do you have dyno numbers for any of the other combos you have run?
Bluevenom867:
You really stepped up to the plate. It will take some time for me to really look over all the great data you brought over.
What I would really like to see is a comparison between TW heads and others that includes flow number for the head and relative hp increase over a baseline. This would be the best way I can think of to compare heads, and get an idea of how flow numbers (and other factors?) affect power output.
The only other combo from above that I have dyno numbers from is the 393 with victor jr's it had a flat tappet cam, victor jr intake and a 650 silver claw carb 10:1 comp and running a loose convertor (5500 stall) it made 377 @ 6100 and 452 ft lbs but it ran well went 10.77@ 124 in a 3200 pound car I have not yet had a chance to run the brodix since the extra work because of working with the outlaw car but before I had FTI do some extra work to them they were put on a NMRA rengade car and went 9.01 @ 154 and made around 825 rwh with a 349 and a ysi blower.... like I said the bottom line is how much cash you have... and what is the total set up going to look like? a smaller head will run good create more boost with the smaller ports but this also creates more heat.... a better fit head will run cooler and more efficient especially on a larger cubic inch motor with a blower

I will have images of molesting stuffed animals in
Heh,I also have a set of CHP CNC/Custom hand work TFS "R" heads.They flow 380cfm @ .720 lift Intake and 260cfm @ .700 on the exhaust

Thats will be the "Race" set-up.As I will go to a large solid roller cam and bigger headers and carb.

I know MM&FF did just such a test.I know AFr's web site has all the test stories.
www.airflowreseach.com,go "Articals",then go down to the bottom and look at "Ultimate Guide to 5.0 Cylinder Heads!".

OK, now I'm jealous
