David Vizard, Uncle Tony's garage, Unity motorsport. Mission impossible Dodge 302 Head porting

Well, if you have little experience with a port, which I'm pretty sure he said he had, and then your in a competition with someone else on modifying that port, then I guess you're going to put in a lot of time to see what can and can't be done.
Not to mention he may be looking to pick up some porting work from this, so the learning time plus the online exposure is an investment.

My view on something like a SBM head is that it’s just not that much different than the stuff he’s often working on.
When it didn’t show a noticeable improvement after about the 4th of 5th time on the bench, I’d have taken that as a sign, along with my previous years of messing with that stuff(like he has), and know it’s time to stop.

But, he was a good choice for that job.
I’ve seen him spend countless hours messing with “science experiment” heads in the past.

The 24hrs he has messing around with R&D on that one intake & exhaust port is more time than I’d spend on the complete porting job.
