Just picked up a pair of Brodix street heads for a song, but don't know the specifics on them, they are street heads with a built in heat crossover and have the stamping "STR" above the Brodix logo on the side of the heads. On the end of each head the #'s : 158-1021001. I believe they are 64 cc chambers and they are straight plug heads, but need to know the chamber volume and intake runner volume for sure, as well as what spark plug to run and what the spring height and pressure were set from the factory. I e-mailed Brodix, but have no response yet. Anyone have experience with these heads?

Just an F.Y.I., I'm running these heads on a +.030 327 small journal engine with eagle rods,2 valve relief keith black hypereuectic pistons and an early offenhauser low ram intake with a single quad top and 3310-2 Holley carb. I'm looking at the heads before I choose the camshaft, this will be primarily a street engine in a streetrod (1935-40) ford with 2400 stahl in a t.h 350 trans and 3.70:1 9 inch ford rear

Hello, I googled that part number and the Ik200 came up

I have a set of these heads and I DO NOT remember seeing what you described as an STR over the brodix logo(might have a number or 2 wrong???). To find all the info you need just go to brodix's website and look under IK180/200. Also personally I love my set of heads, they make good power with 355 with a 268/276 60103 cam.

My Brodix heads are an earlier version, not the IK (iron killer) like yours, I did receive the reply from Brodix, the heads I have are a 170 intake runner 67 cc chamber street replacement head that were ported and polished by brodix after the purchase, they are strictly entry level street performance, which is just what I wanted for this project! I think I'm gonna break out my nos G.M. 097 mechanical camshaft and stuff it in for some 'ol school exhaust notes! I'm waiting for my rotating assembly to return from the balancer, so I'm polishing up a set of the aftermarket early corvette valve covers for it as well

I was after TickFlow heads but Summit had a month waiting time on them.
I had just a week free to do the job so after searching and comparing I went with Brodix IK200s and was´nt disappointed.

Nice!! My heads were semi-polished when I got them thursday, so I took them straight to my polisher before giving them to my machinist to refresh!

I guess you learn something everyday, I didn't know Brodix made a 170cc heads. Here is my 355 with the ik200's on it. (these pics are old, I know)

the 170 heads were their response to the new c.a.r.b. regs, they had them registered with carb for a California # it was actually cast into the exhaust runner externally, they were a nice street entry level head with after market springs 2.02,1.60 valves and screw in studs. as well as the thick deck surface for custom milling to decrease the chamber volume. I'm just tickled to death that I scored them for $600.00
