we usually run stainless valves with some cleanup around the valve guide. We take a 1.88 and cut it down to 1.82. This avoids valve shrouding. It would be nice to find the 3.625 bore sized head gaskets, 3.635 @.040 over. Using the standard Felpro gaskets creates a small area in circumfrance around the bore. Possibly creating a hot spot.
Port velocity is not bad, actually just right for a small motor[/QUOTE]
Thank you! I'm not really up on heads, do they have the hardened seats or would I to have a machine shop go through them?
