As far as the inline valve heads go it rates with the best of them. I'm running mine with 2.05/1.60 valves and shaft rockers. Headers are no problem, Hooker,Mac, and most of the custom manufacturers make headers for this head. If I'm not mistaken, Canfield has the 3/4 in. raised exhaust port also.
Nope, Mac makes a long tube for this combo. So does Hooker. I know that Kooks and Coast Hiperformance does too.
I'll have to wait and see what type of improvements TFS has done to the Street Heats. I had mine CNC ported way back in 1996. I didn't get a flow chart with them that tells me the cfm.
Right now I'm still leaning towards the 205 AFR's for my next 377 stroker. The mid-lift numbers are outstanding. Check out the Total Engine Airflow web site for more info.
