VALVE GUIDES & REAMERS

JIMS ® VALVE GUIDES

• CNC machined. • Special hi-temp, Viton ® O-ring to prevent oil infiltration between guide and head. • Tapered and radius nose for easier installation and better intake and exhaust flow. • Special no-slip serrated valve seal surface: use either OEM style or teflon seals. • Unfinished I.D., ready to be honed or reamed after installation. • Micrograin Cast Iron or Manganese Bronze. This long lasting bearing material allows you to fit the valve at a tighter clearance for better heat dissipation and longer life.

HIGH-PERFORMANCE MANGANESE BRONZE EVO & TWIN CAM TO 2004 VALVE GUIDES Shortened seal area and tapered for use on high lift and high flow applications Use with .530” valve seals.

SHOVELHEAD & PANHEAD 1200cc 1948-79 VALVE GUIDES CAST IRON Use on stock replacement applications with OEM valve seals, or may be machined for use with .530” Teflon ® valve seals.

SIZING THE GUIDE, THE JIMS ® WAY!

HIGH SPEED STEEL & SOLID CARBIDE VALVE GUIDE REAMERS These unique reamers feature a 2" long pilot for perfect alignment with the valve guide while reaming. With these reamers you can expect to ream a valve guide to exact dimensions without any taper in just a few seconds.

JIMS ® Manganese-Bronze valve guide reaming instructions A. Install the cylinder head in a vise. Protect the cylinder head with a clean towel or rag, as pictured. B. Insert the reamer pilot in the guide and lubricate with a good quality cutting oil like K-Line Bronze Reamer Lube. (Fig.1) C. Ream at 100-200 RPM with

a slow feed rate. Let the reamer do the work and do not force the ream- er. (Fig.2) D. After reaming all the way through, pull the reamer out with-out stopping the rota- tion. (DO NOT reverse rota- tion!) E. Clean the chips off the reamer and you’re ready for the next valve guide.
