Amazing flow numbers. Finally something for us N/A guys.

"The unique valve gear arrangement made possible by Arao Performance's patented head design (US Patent #5,007,387) allows rev's to over 9000 RPM without use of exotic valve train parts or freakish valve spring loadings."

 

I don't mean to be rude, but do a search as this has been discussed here about eleventy billion times! Sorry, but I am just feeling testy and hung over right now after a weekend of Holiday parties.

I think those heads have been around for at least 7 years. Second Street Speed did the flow test for the first LT1 set back in the 90's and the results were published in GM High-Tech Performance agazine.

If you would like to see an actual set for an LT1, check these pictures.... he's had them sitting in his basement for at least 4.5 years.
