18* head flow numbers inside = ) well finally i have heads that flow great.
Brodix 18c
Lift intake and exhaust at 28" drop
.100 64.6
.200 129.4 128.2
.300 198.1 191.4
.400 262.0 232.5
.500 314.3 252.0
.600 347.9 262.2
.700 373.9 267.2
.800 378.3 270.0
.850 378.7 270.2
Im very happy with the results.The heads flowed within 2% of advertised. The exhaust outflowed my brodix 10x unported on the Intake side lol.
the only thing i have left to do is pick a cam.Im thinking of going with cam motion.What cam and/or cam company do u guys recommend???(anything but comp cams)

looks like some good #'s. how much lift are you actually looking at making? and what's the setup, turbo or s/c?
Im going NA with my motor, nitrous maybe later.compression should be in the 14+ to 1 range.Flat top pistons netted 13 to 1

oh, ok. i didn't realize this was a race application. so what kind of car?
i'll take a stab at the cam size not knowing how many cubes you're running=276 @.050 intake,284 @.050 exhaust,.710-740 lift with your rockers.

Nice numbers! I will probably be selling my Brobix 18* heads to pick up a set of CFE 18* heads.
To use them on a LT1 they need to be converted. I will be using mine on a LT1
I already have a Hogans Intake ready to do go.
I also order all the company cams through Cam Motion I try to keep lift in the low to Mid .600s so valve guide wear is not an isuue for a street car
BTW what CC's are the intake ports and the chambers?

I should of gone with a Hogans manifold too but at the time i was tossing the idea of going with a carb or fuel injection. So undecided i went with a regular intake manifold instead.
the chamber is 53cc and the port is 280 cc

LOL the arguement of the decade! I still have an LT1 block and it is reverse flow and it is an Expensive PITA to get done. Sounds like a LT1 to me!
I sold a Complete LT4 top end to get the intake alone. I was thinking of going 23* RR but figured WTF if I am going to do lets do it all the way
I have most of what I need. I had planned on just getting this set of heads finished but for the price I might as well just buy another set finished and be done with it.here are a few pics
