I want a set of Indy 572-13 385 cnc ported heads badly.

very well said Jim,it would be nice to compare the heads he has now on YOUR bench.

I try not to be stupid, but my knowledge with head flow is really non existant, that's why I ask questions. I like to better myself. Thanks for the explanation, Jim. I promise I'm gonna give you a holler......I got a lot goin on right now and I need to have some time on phone.

iq52 u are without question a very knowledgeable person on this head porting and u explained it better than any book could tell me about porting and smoothing out another mans port work when theres no hope for flow numbers to improve. i can see why u want a bare 572-13 head and not the 385 cc head to start with, thanks for the info, i learned something!

I was going to use my heads I already have in my 63 Plymouth max wedge savoy the way they sit now and upgrade the motor I have with the 385 cc indy heads. the 385 heads will have the titanium valve and with the bigger chamber and a cnc port and then Jim can do his magic or just get a set of bare 385 heads and let Jim go to town on them, I am thinking I will see the results i'm looking for.
I was told that my 572-13 365 cc heads would not make any more power with titanium valves and be a waste of money so I opted for the SS valves in my application I have now.

It sounds as though you didn't read or understand anything Jim posted. He needs the material to be in the port so that he can shape it the way he sees fit rather than the way Indy shapes it. The best thing to do would be buying bare castings and let JL do his thing. My apologies for being rude, but it's not rocket science, it's cylinder head 101.

No problem. My son and I can take the 385 heads, put in 2.350 titanium valves and get you the 425-430 cfm...........if that's all the flow you want.

Son-of-a-gun, who can't put in a .050" larger valve and pick up a few cfm. If you want more.......well......we'd like the as-cast heads.

For those that are curious... From INDY's site/prices... $1895 for the bare 572-H1-13 365 INDY wedge heads, {for 4.50" bores} need to be ported & valve jobs, $4321 for ported/assembled 572-13AX, they're near $7k for 365cc or 385cc cnc' ported in total kit form, you can do allot with near $5k in porting & parts... $2195 for the bare 600-H1-13X {for 4.563" bores} need ported & valve jobs, they are $6527 assembled & ported 600-H1-13XAS, then near $10k for the 425cc cnc' ported in total kit form... they don't show cfm flow, it's listed in port volume cc's

Indy lists the Windjammer CNC porting for those heads as follows:

572-13 365cc CNC is 395cfm @ .700"

572-13 385cc CNC is 410cfm @ .700"

600-13X 460cc CNC is 500cfm @ .800"

I'm pretty sure the reason they would tell someone you can't get the flows from the 365 head, is to sell another pair of heads. I find it difficult to believe that there are two different castings for the 365 and 385 port jobs.

Jim, I was just throwing out what I know from what I have heard from 2 other racers that use the 385 cc heads.
Id rather just get the bare heads and let you do your magic as long as you feel comfortable banging away on those ports. Just want to make sure we can get as much flow as possible because its a full blown race engine with the best parts money can buy. Just let me know when you want to start. thanks.
