340 X head advice

Sell those "desirable unobtainium" X heads to some numbers match type guy for $400 or what ever they go for these days. Pick up a set of any 360 casting for $50, the profit off the X heads pays for the machine work. Now you're into your heads for next to nothing. FACT!

I'm all over that idea when that's what you have to start and are looking for over 260 cfm. J head is imo the best casting head of the bunch, but my X heads as of this second flow 257cfm by .500 and it took way less than the intro to a port job heads, for damn fking sure.

Sell the heads and buy speed masters then, because for all the ******* trouble you're gonna go through selling and buying and then modifying.... you'd have to be a knothead not to.Finally got to the day and age where people tell you to sell your xheads in order to run a marginally better head.
50 bucks...for j heads, may be 10+ yrs ago.
100 a pair, not mag'd, in cali... is the rate
I have respect for you guys, but really?

Send the op heads and save him from those dreaded x'ers.
