I'm getting ready to port and polish my cylinder heads and i want to know which method you guys prefer? There is standard abrasives kit for porting and polishing heads and there is also the carbide burring kits. Which way should i go and what are the advantages and disadvantages? Any input is appreciated.
Thanks,
Dane

 

Carbide cutters all the way.

The SA stuff is cheap and won't last long enough to do both heads.

The carbide cutters are less expensive and will definitely last long enough for a couple of pairs of heads.

 

that was the way i was leaning. thanks
p.s. - ive read your thread on porting and polishing heads. you've really helped me out alot:hail:

 

Yeah, definately carbide...that's all I used when I did a set of '416's this past winter.


In this thread there are some good pics of how things should optimally turn out and also which carbide bits work best:

how long can i expect to take doing my l98 heads. I want to take my time and make sure i stay consistant.

 

To do a thorough job you are looking at 30 hours. That's for a first time p and p job.

Take your time, you won't regret it

 

At the risk of being contrary, I'd say "Both".

But there I go again.

 

I agree, both.....

The SA stuff is quite expensive to use for an entire port job, because you'll go through so much of it. But, if you use a carbide cutter for the heavy-duty metal removal and use the SA products for finishing, you get the best of both worlds.

 

Both.

Carbides for the big dirty business, SA kit for the rest.
