Proflow Cylinder Head SuperMax 210 & Intake Kit, Manifold, MaxJr, Single Plane, Square Bore, Aluminium, Black, For Holden, Commodore V8, VN Heads 253

A-356 alloy heads, MaxJr single-plane. 253 VN V8 kit.

A complete top-end kit for VN-head Holden V8s that doesn't cut corners.

• ▸A-356 aluminium castings keep weight down without sacrificing rigidity
• ▸Phosphorous bronze valve guides handle heat and wear reliably
• ▸Ductile iron valve seats run safely on pump unleaded
• ▸Single-plane MaxJr manifold favours mid-to-high RPM power delivery
• ▸Square bore carb flange suits most common four-barrel setups
• ▸Kit ships with valve covers, intake gaskets and bolts included

Budget heads often cut costs on valve seat material or guide alloy — the SuperMax 210 uses ductile iron seats and phosphorous bronze guides throughout, so longevity on track isn't a gamble. Bundling the MaxJr single-plane manifold, valve covers and all hardware into one kit removes the guesswork from sourcing compatible components and keeps the total spend honest for a serious build.
