Absolutely! gasket match port your heads and intake. I am using the 1262 gasket set as my guide and performance is awesome.

If you blew the head gasket, you need to find what is making you lean out. It could be your ignition timeing is way high, it could be a carburetor issue. It could be poor gas. I just spun a bearing. When I tore down the engine I found 4 broken top rings. DETONATION. So I will cut back my ignition, run better fuel, and richen up my jets when I race.

Cut your double plain intake to match what Edelbrock does with their RPM air gap unit. They notch the divider to get better cylinder to cylinder mixture at high RPM. You can do this with a dye grinder and a bit, but make sure to smooth everything. No sharp edges anywhere around the air fuel system or you will get fuel separation issues.

I would gasket match the exhaust ports too. You might consider using a hooker competition style header in order to up your exhaust flow. Hopefully they ported the exhaust side really well. That is the weak point of a stock small block windsor head.
