For Hydraulic Roller or Solid Flat Tappet .600" max camshafts
These reasonably priced PBM 200cc intake port small
block Chevy cylinder heads are available in two stages of performance.
The "Street Ready" version feature here has "As-Cast" intake
ports, while the higher flowing "Race Ready" versions featured elsewhere in our store
have 100% CNC porting in the intake, exhaust and chambers. Valves are
stainless steel 2.020" intake and 1.600" exhaust.
The exceptional flow characteristics, 23° valve angle,
and standard valve spacing make this the perfect head for 383 to 400 cid
engines in bracket drag cars, sportsman oval trackers, and modified
street cars operating between 2000 and 6000 rpm (higher rpm ranges
possible depending on combination of parts).
These heads are not for every engine combination so if
you're unsure whether these are the right heads for you, we always
encourage you to contact us directly.
