d16a6 or d16y8 head?
ok so im looking for some opinions backed up by some reasons here. i have a d16a6 head with ferrera valves that will be lightly ported and polished, but would need a 3 angle on it. or i can go with my d16y8 head with stg.1 comp cam, havent decided on pnp yet. both heads have fewer than 60k im pretty sure a6 head is a remanufactured head with less than 10k on it. i will be running a zdyne super ecu, and either head will be on my 130k mile b2 block. i plan on 6-8 psi hmt setup. i just cant decide wich head? i want abouy 170 whp, so anyone with suggestions?

i appreciate the reply, kinda nasty but its a reply, just trying to get some opinions on a good route. logically the minni me would be the choice, but at 8 psi its close to the threshold of the blocks stock potential. on the other hand the a6 head at 8 psi is a safe number but not wuite what i want, lol hence the reason im looking for some opinions that may sway me one way or the other.

, im probably going to go withthe 14b, unless for some reason i get ahold of a cheap t25.
, im probably going to go withthe 14b, unless for some reason i get ahold of a cheap t25. it will hold boost MUCH better, and be alot easier to tune without having a crazy high CR, and the extra displacement really helps.
They are also fairly cheap.

Re: d16a6 or d16y8 head?
i got a b2 block with a y7 head right now and the cr is scary high for a dd. 10.7:1 isnt the best for gas millage. then again i get about 22-25 in the city and about 30-35 on the highway. its a peppy little motor though. it would benefit from a si 5 speed instead of my 4 gear terror. and yes since i was the first reply i had to be a dick. HMT homeage to noobs.
