Either way make sure you key it. We have seen the stock pin start the sheer.
You ever have that one person who responds and ultimately give no ****s about his opinion?
A stock cam and head porting will requires compounds of nitrous to force volumetric efficiency.
With a cam and headwork increased volumetric efficiency will be had with a cost to drivabilty.
So if you are looking for a big single and top end power than the cam is a must.
A mild set of twins will perform fine stock and drive great.
There is also a bunch of wiggle room with good tuning.
That's just my take on it in a nutshell.
I have zero drivability issues with ported heads and large camshaft.
