Heads

[ForcedFirebird]

I think the perception of porting is different between those who do it a lot and those who have done light porting with a dremel. I have no doubt that 3400-95-Modified's heads are better than stock, he did a very nice job however when a person does a "competition" port job like Ben, John and myself there is quite a bit more to the process. I think Ben can vouch for the amount of material removed from the ports on my 3500 heads.

I've got 2 hours of porting into just a 3500 UIM and LIM that are on my bench, probably another 6-8 will go into the heads. That's with an air die grinder and a nice set of bits. I'll also probably spend another hour or 2 working with them on the flow bench to match all the ports and give the customer final numbers. It is not an easy process.

Yeah, and you guys need to do some iron so you can appreciate the aluminum more :P

Imagine having to remove that much material, and more using a double cut burr and stones hehe.

I also like how you brought up the bench time as well. People who don't want to pay the price for a good set of heads doesn't realize the time and effort that goes into them, and don't take into consideration the amount of time invested initially (hundreds of flow tests, building a bench, research etc). That time has to be spread out across several sets of heads and/or manis, otherwise the first set of heads would cost about 10x as much as the 10th set.

So in theory, iron heads are harder to screw up because it takes 10x longer to remove material, lol.

i think i already asked this somewhere but i cant find it. whats the difference between regular ported heads from WOT and the competition series heads?

also when i get them from WOT tech..is the price per head or for a set?

Competition has the detail work done, like polishing the exhaust port vs just shaping it and leaving it as is after the carbide cutter work. Pricing is for the set, though a refundable core charge applies.

Kinda off topic, but would it ever be possible to have a set of heads just ported to Competition level, no valves, no springs, no locks, no seals... just port a set of castings and return bare. Also if necessary to compliment your port work I guess cut the valve job, unless the valve job is nothing special to the port work.

What would that run? You don't leave an option in the store of just having the castings done and leaving it to the user to assemble with parts already owned.

bump. im interested in 3400-95-modified's questions as well.
