Some parts I have been specing out for a Ford 200 build with the exception of the valve springs and cam choice these parts, with proper conecting Rod prep, and a good piston choice should be quite capable of 6000 to 6500 RPM.

Ford Log Head 3/4 Exhust Port Divider @ Vintage Inlines for $25.00
Here it is, the controversial port divider! The theory is that if the siamesed #3 & 4 exhaust ports are separated, the resulting "balance" will help performance. If used, this piece must be installed per the manufacturers instructions! Do not do it any other way. Tack weld it in with a nickle...

Clay Smith recommends for some of their Ford Six cams that the closed valve spring seat pressure be set at 120 to 130 pounds. The Valve Spring I have been looking for is a 302 V8 type Spring with a Dampner they are the old Clastic Inlines part # CSC-200-STY (by Clay Smith Cams) so far I haven't been able to find them listed on the Vintage Inlines site. They have a little more seat pressure at 100 pounds with the Dampner to cut down on the harmonics. Clay Smith might still know of these and if they carry them or one that is a better match for their current cams.
For example for the Clay Smith cam listed below that has .468 gross lift using the 1.5 ratio rocker arms the Valve Springs will need to have a minimum of .528 clearance (more is better) before going into coil bind / or stacked solid and there should also be enough clearance between the bottom of the valve spring retainers and the top of the valve stem seals so they don't touch at the full valve lift of .468 (again more is better) this is when using the 1.5 ratio rocker arms.
For Larger Diameter Intake and Exhaust Valves they are available @ Vintage Inlines and "SI Valves"
http://sivalves.com/pdfs/2016-SI-Catalog.pdf
They make several sizes of larger Ford 200 / 250 Six intake valves and one larger Exhaust Valve, Vintage Inlines may also have these though I haven't been able to access their listings yet.

1.760 HD SEV-3007-S
1.800 HD SEV-3008
1.840 HD SEV-3008-S
