I'm a rookie compared to you guy's as far as quench, flow number's and such, But I did want to point out to other rookie's & newbie's as to WHERE K.W. put his money....$2400....on heads he already owned ! Those shaft rocker set-up ain't cheap, but they eliminate MOST of the parasitc (sp) drag that the stock SB chevy is known for. I'd bet money that they are easily worth double digit HP over the stock set-up.I'm pretty sure that I'm in the $10K ballpark. Big ticket items:
Freshning/machining (for the shaft mounted rockers) the heads (already owned) plus new custom length Valves and Valve Springs about $1600
Shaft Mounted Rockers about $800
As you were, Gentlemen.
