[Fot] Valvce Guide Clearances for Cast Iron Guides?

[Bud R]

Listerati,

What clearances should be run on Spitfire 1300 intake and exhaust cast iron
valve guides?

Stock plus 0.0005 inches? One source says 0.0008 intake and 0.0015 for exhaust
are stock.

Please tell me your thoughts on those clearances, or if you know what they
should be, or what youve successfully run them at. Adding in the additional
0.0005 would give me 0.0013 intake and 0.0020 on exhaust. Seems a little tight
eh? This is for a race engine BTW.

Thanks
Bud Rolofson
