Custom head build thread
Hey guys,
Ok so i have acquired a factory head this weekend, and am planning a build on it. I'd love some of the people that have done this before to chime in here. My plan thus far is port & polish, larger valves, (spings maybe) and a different cam. Suggestions are more then welcome being this is my first attempt at something like this. here are some pictures of what im working with thus far.

I won't be doing any of the machining, that's a skill that I don't have . I'm just trying to figure out what parts to use as of now, and how they compare to the heads that are on the market. I will also post the before and after flow sheets when they become avaible. Any sugestions on cams, or valves?

Good for you for doing you own thing. Every one seems to just follow the crowd on here. Here is some reading for you to do. Good luck

Good for you... making your own HP is ALWAYS fun.. ( with work)
Unless you are going to RACE the car.. push High RPM ( 7500+ ), have a radical camshaft, the STOCK Valve train is extremely strong, and the expensive bits are not needed!! ( amazing huh??) to want them, is different, than needing them....
Valve size is in direct correlation on your application.. if you can live with a loss of the low and mid range,and are mostly in the 5500-8000+ rev range, then the a BV size will be rocking!! If you are a street driver, with the weekend track runs once in a while.. the smaller( Medium size) valves are the way to go. Even the stock size will pull a LOT of power up to 7100-7300 revs!! SOOOooooo.... save a buck or two and you dont need all the dual chrome / aluminum spaced/ super trick valve train stuff for a 250+ HP MINI!!
Porting for a NOVICE is good as long as you dont get caught up in the BIGGER is BETTER thingy.. the increase in power will be good with the basic work. Trying to eek out a lot of flow and power without knowing what you are doing can and WILL hurt you. "KISS"!!
Have fun and find out how food tastes with aluminum !! LOL
Just me..............................

Thanks to everyones support!!! getting me more anxious to get this ball rolling!
Thumper,
i was planning on this head being more for a race application. I really want to "get as much as possible" out of this head. my car has a ton of low end power now so id love to have more high end. as far as the porting goes i was going to start off with just gasket matching it. Good, bad?? also...if i were to do dual valve springs what would that do for the head?? just make it more durable? this is a learning process for me so please bare with me

Must use their parts in systems:
You could potentially measure the OEM spring to find a matching ferrea spring to make use of OEM retainers/locks. It wouldn't nesscessarily match to what Ferrea offers specifically for the MINI according to the catalog. You would really have to know what your doing to go this route.
Ferrea components are considered by most to be the best.
- Ferrea Valves require their retainers and locks.
- Ferrea springs use OEM locator, ferrea Retainer, ferrea locks, and ferrea valves.
- You can use the valves/retainers with OEM springs.
