I have ported several sets of heads over the years. Definitely is an art that takes patience. And well worth doing.
As always, professional advice from Davin. Thanks
Thanks Davin. Cheers guys it’s interesting. 👍
Davin would make a good dentist. Just needs a smaller grinder.
😂
My teeth hurt listening to this…
No offense but i’ll need nitrous for sure lol
A good tip when porting heads is to occasionally dip the burr in Johnson’s Paste Wax. It helps keep them from clogging up with material especially aluminum.
The guy has star quality
Always learning something new here. The details that make all the difference. Thanks!
just polishing and removing casting marks improves performance….. without porting just polishing
Invest in an American made die grinder. Henry & Dotco are some of the best. Thousands of hours of work in these!
What’s fun if you have access to a bench flow tester is what the numbers are before and after deburring the ports and if you want to know the percentage difference polishing effects the flow also you can check it.
You are correct VetteKid, and realistically without doing that you are just guessing what improvements you have made/ causing each cylinder to have different amounts of flow rate
Thank you for sharing this technique. 🇨🇦😎
Love it – DIY head porting 101.
Disconnect the air hose before change the burr.
Now I know why it is called a lapping tool after he licked it . . . .
Great mini-tutorial for folks that have heard talk about porting and polishing the heads but only had a vague idea of what it really meant. Thanks again for the high quality content!
Im going to practice with an extra head before i start my build ..great info thanks
Buy a cheap used chainsaw from Craigslist to practice on 👍
@Old Griz naa my truck is 4 stroke not a saab sonett
If I could offer some advise, start with a sanding wheel and once you’re comfortable with it, then use a carbide burr. The carbide gets away from you so fast, you can make a mess before you know it. Sanding wheels are very forgivable.
@Iron Panther o ok thanks
Love these longer videos, indepth and well explained!
I would love to hang out, chat, help and learn from you, ….This is a great show.😁👍
So tired of this COVID Crap and want something to go do before I drive my wife and kids nuts!😳😬😨😱
But make sure you wear a mask when you’re porting heads, I’ve done alot of it & rust isn’t great for a person’s lungs.
1960’s and 70’s heads have huge amounts of casting material left over inside the heads , by the 90’s they got better.
what about the 80s
So as with most things, it’s a matter of time and money. Two sides of the same coin. And you get what you pay for. Good vid. 👍🏻😉
