FREE HORSEPOWER UPGRADE FOR ANY ENGINE, (gasket match porting on cylinder heads) BBC 454 SWAP
In this video I port my my heads to exhaust gasket and intake gasket to try and free up as much power as possible for my big block 454 Chevy engine. Used a die grinder with a carbide bit for the majority of the porting then used a flapper bit to smooth and polish everything overall turned out good obviously I don’t have a base mark for the actual power/ performance gain on doing this but I believe roadkills engine masters did a test of ported intakes and heads so check them out for my scientific stuff lol. Thanks for watching hope yall enjoy and try it yourselves it’s not hard to do and best part is that it’s free.
