The only real draw back i see to useing that head is that they were more prone to cracking when over heated then The Non intreagel heads. It is also to my understanding that,That Head had a mild lump to the Port? I don't know for sure Because i never cut one up. To see if this was true or not. And the other question i guess would be Just how small Or big are Those ports & how well would they even flow. compaired to a Non intreagel head with a Lump port. Also That head was ment for all the emission, and Not for any type of performance.That 1000-1500 Is that for Out the door Bolt-on?? Or just to have it cut up and ready for reworking??
