well my first bbc had a set like that over 30 years ago it takes abit of work to get them to fit a with roller rockers and a hi lift cam and more mill work for the moon breathers it the only way to go with a blower .i pull one of the plug s that the two blown 502 offshore engines where dyno out with it was one step up hotter then i told you to use them engines were low boost with smaller blowers then what you have but makes over 600 hp on pump fuel so i think your ok .when time comes i will tell you or set up the dist curve and help you tune it in
