R-16 Competition/Stroker Valves & Guides

[JT68]

Years ago Datsun Comp made oversize race valves for the R-engine- Those are OOP. We just CNC'd a run of them here in GA. USA production from top Quality SS blanks. Hardened tips. Available now in these sizes:

Intakes 44mm (+2mm) 145/set

Exhaust Choice of 33 or 34mm (+1 or 2mm) 145/set

33's are an excellent fit, just requires moderate seat and porting skills.
34's require expert seat and porting work, so you need a good shop to prep for those. (Highly recommended)

All 3 sizes are 11/32" stems for standard guides, so guide changes are not necessary.

Ask us about small stem, ultra-light-weight-performance valve sets!

Note these are not budget, off-brand, or unknown China-Taiwan valves- all top shelf, custom made-in-USA pieces.

Top Quality, CNC turning center production German Silicon-bronze guides also available (twice the life of iron guides) for ALL Roadster engines.
