FE Technical Forum / Gasket Matching Opinions Wanted
« on: July 14, 2019, 11:12:36 PM »
Hey guys, looking for an opinion on whether or not to gasket match my heads and intake. I feel like I should know the answer to this but my engine building experience so far has been pretty much bolt together affairs so I want to consult the experts before spending money or time and effort that might be detrimental to my goal in the first place. Basically I'm building a 427 (stock bore and stroke) with edelbrock medium rise heads and a BBM tunnel wedge intake. For fuel delivery I'll be using a FAST or equivalent 2x4 fuel injection setup. I know that the intake I'm using is large for my cubic inches. That being said, the intake ports on the heads and intake match absolutely perfectly right out of the box; it's like they were cast together and then cut apart. I still plan on installing larger 2.19 valves in the heads, but would there be any benefit to gasket matching the heads and intake to a larger size? It is going in a light street vehicle with normal street operation. With the amount of cubes I'm running would gasket matching kill any port velocity I have? I realize it would move the power band higher in the RPM range but it will be a stop and go/freeway car in the first place. Sorry for being long winded.
