Poor example as the 307 roller motor uses a totally different cylinder head design. I can however see the issue of using a "stock" roller lifter. Very heavy.
I'll stand by what I've said, REAL RACERS will FIND the parts that they need.
And if they can't find the parts then maybe it's time for them to start building newer combos.
