What do they flow? What is the series # of the heads? Serial numbers 2000 through 5000 had valve clipping issues.

From what I know the Trick Flow CJ heads didn't have the valve clipping issues. The Ford Motorsport/AR heads did.

200 300 400 500 600 700
in. 135 210 278 314 322 329
ex. 96 135 171 201 216 211
heres the numbers for everyone to see.
they are under 2000 on the serial numbers so no clipping issues.
oh and comp cams guideplates not manleys.
got pics if serious email me.


the clipping of the valves were around 700 lift or higher on the 2000 thru 5000 serial no. heads with the 2.25 valves.im not sure if the trick flows had the machining error. i thought it was only the A429 heads.

Oh, sorry bout that. I thought they were the A429 Motorsport heads. Were these heads ported or are those #s out of the box?
