Yea, .. I was told by an industry insider type that they flowed 280 @ 28", .. . .. ..what kind of
flow are other head porters getting from a gsr head??????????

With big cams, .. I would think the +1 intake valve may make cam timing a critical thing, ..

The shop where im at ...i was getting 295 @ .480 lift on a gsr head ...on my old b-20
this is considered a stage one package there

 

The heads are being built by this company http://www.protopline.com/racingaluminumhonda.asp and sold under different names. Here is another example http://www.hrdracingheads.com/....html

Again:

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">Our GSR head is already available. There is no Type R configuration. We purchase the GSR castings directly from Honda, then port them, install +1mm valves, and upgrade the valvetrain components.</TD></TR></TABLE>

 

i'm fairly sure that any competent head builder could outperform those specs...for a much more reasonable price.

 

so are these heads bare or do they come with the valve train?

 

does aneybody have the full flow chart on these heads i need them badly for a school dyno project whoever gets the highest power wins so far with a k series rocker and a stephen papadakas cam im pretty good but i have never seen flow numbes that high at .500 so if anwybody can get me the rest it would be great

 

Below are the full flow numbers as measured on our SuperFlow 600. I also included the numbers we got before our CNC porting.

Valve
Lift Stock In CNC In Stock Ex CNC Ex
.100 99 100 90 92
.200 168 168 152 168
.300 215 236 176 207
.400 250 275 179 221
.500 269 320 178 224

Does these come built or is it bare with only the cam caps?????
Thinking of building a full Dart engine on the sidelines as a spare

it sure is a ripoff IMHO... anyone can find an old B16 head ($100), send it to Portflow or any other head massager, who can port it ($900), drop in valvetrain of your choice ($100+$400) and work the valves ($300) and even offer cams to match the setup for easily much less $$$ complete, compared to a Dart head.</TD></TR></TABLE>

but this one says 'Dart'
