The guide is 0.010 inches larger in diameter than stock. Used when original guides are worn and the bore is honed to accept the larger size.

Will this fit both intake and exhaust ports?

Do I need to have my head bored before installing?

Yes. The cylinder head must be honed to +0.010 oversize to accept this guide. Have a machine shop verify bore size before installation.

Does this fit my Twin Cam engine?

No — this guide is EVO-specific (1984-1999). Twin Cam engines use different guides and bore specs.
