"STREET PORT" Heads, 9.6:1 Compression, Stock TB/Stock Injectors, Andrews TW26G Cams, S.E. Slip-ons

Decent considering not nearly as nice as-cast ports on the earlier heads.

Don,
Looks good.
We just completed an in-house build/install/tune.
80" Evo, Our Stage I Heads, OEM ignition, CV carb jetted, S/E slip-ons, and a Bob Wood 6. Tuned out, on our 150, at 79.9 hp and 91.4 ft lbs in lousey air.
Not bad for an engine 13" smaller, with our entry level head.
