Old 451 - B1-B/S Head 11:1 compression (no quench, entire piston dished) 251/251@0.050 Solid Roller, 33* total timing. OK on pump gas, usually ran 50% pump/50% 110 race gas when I raced it just to be safe.
These next two have about 0.040" quench
New 499 - Victor MW Head, 12.4:1 compression, 272 (or 274, I forgot)@ 0.050 Solid Roller, 34-36 Total timing (still tuning.) Ran OK on pump gas for a very limited time, and did not try WOT on pump, usualy ran on 110 race gas or mix of race and pump. Switched to E-85 last year and still tuning it.
505 - Stealth heads. A bit over 10:1 (I think 10.3:1?), 236/242@ 0.050 hydraulic Roller. EFI so timing varies with load and I'm still tuning this. Pump gas only, but it has pinged before (don't know the exact timing because I was using the Edelbrock XT hand-held EFI controller and changing the global timing.

Street or Race ? Lots of Race responses, so I'll give a "Street" We just put 10.8:1 static on some Ported Stealths, used an XS282S Comp Solid Flat Tappet with 1.6 Rockers... good for 587 hp/ 592 Trq on the SF902 with 91 Octane, 33* BTDC
Better to be a "has been" than a "never was".

We Ported a very Fat curve on our SuperFlow SF750 Bench, but just under 300cfm @ .600". I can post the Flow Sheet if you like ? but off my head I think 285cfm by .500", 291cfm @ .550" and 297cfm @ .600". About 10-12 Hours Port & prep. NOT cost effective to spend any more on what is really an "entry level" Cylinder Head ?

Was that a stock stroke 440? 400 Block based "451", but yes stock 3.75" (440)Stroke. Thats a strong running engine, darn impressive for a somewhat mild cam
