Yes belzona is the master of reshaping ports for higher velocity in ATV and 2stroke drag engines I have built. I have honsetly cut the entire port out of banshee's and many 125's and also a couple SBC heads and rebuilt the entire port cross section with belzona then re-ported over the belzona.
Check out some of the belzona tricks I have used to raise this LT1 intake port roof without having my buddy weld it.
I have also ported and used belzona in 80% nitromethane burning drag dirtbikes and many many many 50,000rpm nitro rc cars, that epoxy WILL NOT BURN OUT!!!!!!!! It has a great expansion and cooling rate that is very close to aluminum and I have litteraly baked the stuff with a torch trying to make it fail. It only gets stronger the longer it cures. I have also used it to fill bolt holes and redrill and tap the belzona area to fix major stripped holes and cracked spots in intakes. Also have fixed many gasket area's on intake gasket flange where people have gotten to aggressive with the die grinder.
So defintly take your grandpa's advice and use this stuff, I bet he knows the exact ratio of the two epoxy's that need mixed for different tensile strength. I used to mix up a different ratio's of it to fix different kinds of parts, like a-arm's and hubs just to get home

ROFL - I had already thought up at least 20 uses for the stuff (both for my real 1:1 z28 and a bunch of rc cars I have) until I saw the cost. WOW.

From my POV some posters are putting too much emotion and off-topic chatter into this thread. Comments regarding Lloyd's character or integrity should not ever have been brought into this thread. Stay on topic and comment on the product not the porter. Rather than put judgement on the porter, let his work speak for itself. Either the product meets with your approval or it doesn't. If it does or doesn't and why is the topic of this thread.

I agree with the fellows, which say he's a great guy to deal with, spoke to him and sent him at least 50 mails; he answered them all. He went beyond to what is normal to get the heads sent back to me. Being a nice guy and quality are two different things.
But like Arnie said, "Let his work speak for itself and either the product meets your approval or it doesn't. If it does or doesn't and why is the topic of this thread".
I personally would pay more, therefore have very good quality than just some sleek looking ports with all having different shapes and volumes, way too big of a combustion chamber and never have been flowed. I had to rework most of the intake ports and combustion chambers myself.
It really was a bargain with all the work that was done to my heads, but like I said, I would have gladly paid more for more quality. The problem is, most people buy heads or have them ported without checking and measuring after they arrive. I might be one of a few people with the knowledge and tools that scrutinize everything they buy, and strange enough I find quite a lot of things that are not the way they should be.
I certainly won’t buy a cam from Bullet anymore or have heads ported from LE.

He should have warned you about this before hand and let you decide how you want to proceed.
Advanced Induction asked what my casting # was before I sent them in and mentioned the two problems in regards to porting.. one is the casting thickness and two is the aluminum hardness. Porting allready thin castings can create longevity problems and clamp force problems (not to mention cracking), and overheated castings create soft alumimum which makes it even less strong, leading to sealing problems and blown head gaskets.
They would not port my heads unless I passed both checks, 1 = casting # and 2 = harndess to ensure I have no head related problems for decades of abuse.
Does Llloyd mention any of this before you fork over $$?

The two different spots in this thread that show breakthoughs have nothing to do with the bare casting thickness as the breakthough spots are in machined holes. The hole ground into the exhaust bolt hole is very common and will have zero effect on the life of the heads or engine. The hole in the intake runner shown goes into the head bolt hole and you need to just run a small dab of rtv on the underside of that head bolt to make sure it doesn't pull oil. It is not uncommon to breakthrough there as well and some heads like the ProFilers actually come that way from the factory. It does not affect flow though most often people install a sleeve in the hole after a breakthough for cosmetic purposes.
