Hi, I was wondering if the mexican vortec could still make somegood power, im looking for about 380 hp and same torque, but I know the mexican head are known to have not as much flow, does anybody know if this is true or not, and if so could the heads without porting make it to 380 hp?

 

I've never heard of 062 "mexican" heads. 062 should be 062 should be 062. Has anyone else here heard of that difference?

I think with the right cam you should be fine for 380HP. Roller or flat tappet block?

 

Thats what I thought, but stamped right on the head is hencho en mexico, I realize that gm has plants down their which why it got me confused when people talk about them having smaller ports? how could that be possible if they're making them the same way, but anyway, thanks for your help!
