I just wonder what a good port job with undercut valves would do for those heads.
Most engine builders around here suggest buying bare heads. Then do your port work and put in the valvetrain of your choice. Might end up costing more money, but you end up with a better head than buying assembled heads.
Just thought these might be a good bare aluminum head to start with. If I could find some trickflows bare, I would consider them.
The IK200's may have some good potential.
They look like they have good power potential and are made to be ported to further increase the airflow. The out of the box flow numbers look good for a 200cc head.
They flow about the same as a out of the box track 1 but with a smaller port. More velocity.
Could do a lot with a cylinder head like that. I like the small exhaust port ( standard) fits typical 1/5/8" street headers.
Most of the aftermarket racing heads like track 1's have a large exhaust port that really needs a minimum 1/3/4" header.

Thats what I am thinking. There should be some good potential in those heads. $699 for a set bare for aluminum heads is not a bad price either. Hey, someone has to be the geunie pig. If I end up with some extra money, I might pick up a set of heads!
Well. I flowed these heads (IK200's) and right out of the box I got 265 at .500 and 194 on the exhaust side in 28G....pretty damn good for a new design right out of the box.
They also have plenty of meat on them if you want to do some serious porting to open them up.
I bet yoiu could get close to 300 at .500 in 28G if you worked at it.
I own a pair I had a set of R.H.S 220's but they didnt perform as well as I had hoped. went with these and just done some gaskey matching and what a difference in et and performance! and for the price .. you cant go wrong! I mean you really cant go wrong with a Brodix head in the first place you know? I say buy 'em bare as the assem. heads have cheap seals and locks and stuff .. so get 'em bare and buy some Manley vavles or Ferra or something I say get 'em
Hey guys, just to chime in, I got a set of these ready to go on the IROC in a week. They are a little rough out of the box, but I planned on porting anyway. Lots of meat for porting, and the flow numbers don't lie. For the price, you can't beat em.
I ended up going with some AFR190's. We flow and worked them, also tried different backcuts angles on the valves. We ened up with some great flow numbers. I need to find them to post.
At least you guys can spread the word on the IK200's for everyone.
The downside I heard about these heads is they come as they are and they have no meat to open them up anymore. They are a good economical good flowing head but left with no room for future growth. This information came from a Brodix dealer. They are even advertised as lightweight castings so I wouldnt take a chance in porting them and ruining your heads. They look like they flow like crap for heads you cant really even port anymore. Any other standard aftermarket casting will flow better with some good porting since they will have the extra material to do so.

To retort, I just finished up my port job today. Exhaust port and bowl polishing, exhaust and intake short side radiusing and a little bit of combustion chamber work. There was PLENTY of room for porting here. The intakes are 200cc anyhow, and are about as big as anyone would want to go on a street setup, so I barely touched those. Just smoothed out a tad since the casting was too bumpy, but not polished. I didn't get a chance to gasket match the intake runners, but there is still plenty of room in that respect.
Really, I don't know how you can say there is no potential for porting...because I am living proof that there is. Sure, you might not be able to hog these out for race applications, but for street/track applications, they are fine.
Just for a 200cc port they dont seem to flow all that well. I have seen less heads with some port work flow better especially on the exhaust side compared to those especially since those heads are already cnc ported. But for a street head I would imagine it would be fine the way they flow. I believe if you tried to port those anymore it would really risk the integrity of the casting. Like I said I got that info from a Brodix dealer. I didnt make it up myself. They seem like good out of the box head but for the same amount of money you can get a good set of as cast heads with even smaller ports that may not flow as well. But then you could somewhere down the line have them ported. They would have much more potential and have something else to play around with later on. The Trickflow Kenny Duttweiler heads seem to be around the same price range flow very close but are not lightweight castings so they would have more potential. They also have a stronger exhaust port flow. At that price why skimp on some budget heads. $1000 really isnt a budget anymore so whats a few more bills for some nice quality heads. Personally I would have opted for the Race Rite heads.
