Indirect.
That cam is bigger, not shorter [ in duration ] than a factory cam. You need to compare the 050 numbers, not adv duration. Plus, it has a tight-ish 109 LSA. That is good. But in combination, it has considerable overlap. This means careful tuning. The first thing you need to do is get the idle timing correct at idle, & vac adv connected to manifold vacuum will probably be reqd IF you want the best possible idle quality, idle vacuum & engine cooling at idle. See my recent posts about this in the 'How to ...' section.
Once idle timing is set, theeeen you check the transfer slot-to-t/blade position in the carb. Some people, with big-ger cams, drill the blades for extra air to reset the t/blade position. By giving the engine the extra timing at idle it wants, holes may not be needed or maybe smaller, because the extra timing has increased engine efficiency at idle.
