I recently bought some brodix heads, I couldent pass up the deal so I bought them before lookign up the specs. I havent had much luck on the brodix site though.

the only numbers i can see on them are B65, maybe im looking in the wrong places? so any links to the specs or whatever you can come up with would be awsome.

thanks

 

It looks like they have an exhaust heat crossover. Id sat that probably makes them their 185cc street head. Id also measure the spring dia, if is a 1.45" or there abouts, Id say that makes it very likely.

 

Its hard to tell but to me thoes intake ports look like they might be bigger than 185cc.

 

Looks like a nightmare waiting to happen. Might wanna throw an intake gasket on there and see if it lines up.

 

BRODIX Cylinder Heads Over 40 Years of Innovative Cylinder Head Technology You'll just have to look at the pics of them all and compare. I can tell you looking at the header flange though, they're one of the bigger ones; they have the spread-port Stahl flange on them, instead of the stock flange. They look to me like 18SP but it's hard to be sure.

Yup, looks like Billy Bob got in there and "hogged em out real good". Right in the WORST POSSIBLE PLACE, where it not only doesn't HELP performance, but rather, it HURTS. Namely, the floor of the intake ports.

Basically it looks like you just bought somebody's trash that they already scrapped out, from an overly enthusiastic port job. Which of course explains the impossibly great deal.

It's not going to be any fun at all trying to get an intake gasket to seal with the bottom of the ports knife-edged like that. That's probably why they went up for sale actually; couldn't keep it from sucking oil out of the crankcase.

 

the pic is decieving, the heads havent been ported out, thats just bits of silacone on there so it looks uneven. the aluminum is still super smooth in the intakes from the factory. and a intake gasket looks like it will seal, I think they were only run for a couple passes on them, since surface and new springs, ect.

 

Im still not too sure what heads they are, anyone know if there are any casting numbers on them or other ways to find out?
thanks

 

i am gonna tell you that those heads are the -8 pro/-8 /23°

 

Did you ever get an ID on those heads, i have a set that is very similar to those that i cannot ID so far.

http://www.brodix.com/heads/-8.html these are the closedt ones to them. from what ive found out these heads are a few years old.

i still would like to be 100% sure of specs on them though, before i start picking out parts...

In the first pic..at the top look right next to the bolt hole on the exhaust port.. you see an 8..made back late 80s..and are still a great head from what Brodix says..they are the same as a track 1..or the 23* heads..they were jsut made before..
