Re: Poll: Fel-Pro or Victor gaskets?
I do not have access to a Victor Performance gasket catalog, but here is what I can report from the General Purpose (GP) Victor gasket catalog. The best performance head gasket offered by Victor is the Solicor. The only information in the GP catalog is; the Solicor gasket uses a wire that is "Yieldable" Wire Ring. Solicor SCR & SC cylinder head gaskets provide additional crush resistance and withstands higher sealing pressure. The Victor General Purpose catalog show a cut-away of the Solicor gasket construction. Stainless Steel Flange, Teflon Coating, Non-Asbestos Facing, and Steel Core. I do not know if Victor Performance has a 4.50" gasket. The Solicor gasket is the only gasket I've seen hold up to a blower 454 Marine engine, but it has cast heads. The Fel-Pro performance head gasket did not withstand the blower pressures for more than one season, and the season was cut short because of the head gasket failure.
The Victor Nitro-Seal is the common head gasket offered by Victor, it's construction is similar to the Fel-Pro Perm-torque, but uses a Stainless Steel Flange, Graphite Facing, and a Perforated Steel Core. The Victor Nitro-Seal seems to work fine with a cylinder head R&R type engine repair, when neither the head or block are surfaced. The Fel-Pro Perma-Torque seems to work just as good as the Victor for this type of engine repair. I've even had good results with Detroit gaskets when both the head and block are surfaced, but I'll never try another Detroit gasket for a cylinder head R&R engine repair. I've also had good results with the Victor Nitro-Seal with aluminum head engines also, but I always have aluminum heads surfaced, weather they need it or not.
Victor shows a 502 in the General Motors Marine section of the GP catalog, but it's 4.47" and shows only nitro-seal. I'm guessing but I'd think a Marine 502 would be similar to the General Motors Perfromane Parts 502? If so, maybe Victor Performance offers a Solicor SCR or SC for the 502 with a 4.47" bore.
