318 Poly Flow Test

Dale Davies said

What is the springs installed height. The 1.88" Magnum valves could probably be installed easy enough. For low cost the LS 1.9" intake could also be employed. Get the GM powdered metal guides or bronze. If the installed height is about 1.8" the LS beehive springs, retainers and keepers can be used.

Should be 1.800 OEM installed height from my research previously. I used Pro-Flo stainless valves from REV @ 1.60 / 1.94 with Manley springs and retainers. Camshaft is a reground OEM by Oregon Cams to a Schneider profile I provided. Dale is correct also with regard to using the LS intake as that was done by one of the Engine Masters teams in their Poly build. I'm also running full-length stainless headers for a 302-351 Ford that I made adapters for.
