These heads can be dismal to spectacular depending on the porting. The only way to know is get them on a bench and have them tested. You will see the best results for matching the can after you know flow too. You are merely guessing until you know.

Where exactly are you at...?

I also have a CNC program for those heads, if you wish to go to that extent.

Phillip and Randy are excellent to work with and are very experienced. Engine Systems, in Tucker Ga. is another option a little closer to Macon. Keith Fulp (Wheelie 58) has close ties with this shop I believe.

Keith is just a little north of you and you could carry them to them as cheap as you could ship them.

Here are some A429 ported numbers for the heads that I bought from Dave Freelander. These are the heads from project "cheapskate" in proven builds section. This is a copy and paste of what Dave did/observed.

" Hears what the heads ended up flowing. As you can see a quality performance valve job is worth its weight in gold, I have not touched the intake ports except for the valve job. The valve job that was on these appeared to have only 2 angles and a sharp ridge, but the portwork itself looked rather nice. Lesson here is you get what you pay for in a valve job cost of the valve job $225

it should also be noted the intake valves on the befor did not have a backcut and the after numbers java a light backcut Nd that is also contributing to the excelent intake flows.

intake before valve job / after valve job.

.100 75 / 75
.200 143 / 169
.300 221 / 260
.400 293 / 319
.500 325 / 360
.600 349 / 384
.650 356 / 388
.700 358 / 391

exhaust before, after number are affected by a big ridge that need to be blended out, I'll post numbers after I get after them as the after numbers with the ridge where about the same as before. I expect improvements into the low 200's after I finish blending them.

.100 55
.200 119
.300 167
.400 186
.500 186
.600 188
.700 190

Those A429 exhaust numbers should come up significantly.
Should easily end up around (1.76" valve) :

.200 117
.300 161
.400 200
.500 224
.600 244
.700 257

This was not an all out porting job. Did have a decent valve job.

Some A429's have valve clipping issues with 2.23" valve - beware!
Mine certainly did, and they were not early castings.

Yes mine did also that is why they have 2.23 valves instead of the 2.25...

How much does a CNC port job and valve job run for these heads and what kind of final numbers do they average after CNC porting? Im just looking for a "quote" on the price and numbers.

Because of the different placement exhaust valve bowls on these A429 heads the CNC program does not do the exhaust valve bowls and these need to be hand blended. The port from the exhaust flange inward IS machined by CNC along with the entire intake port.

That Job is $799.00 for the CNC stuff. The guides need to be removed for this so after reinstalling them, a valve job MUST be done either by you or us. A matching competition valve job is $240.00 for the valve and seat work.
