Doing a little port work on my canfields
Friday, April 6, 2007

Hey guys I am back, this time with some of the cylinder head work I been doing on my canfields I received this week. This will be my third time using canfield cylinder heads on a small block ford. The first time I used the 195cc canfield 58cc chamber on a fairly radical 306 inch small block. The second time I used the exact same head on a street driven 347, and now as you know this set of canfields is destined for my 408 inch small block ford stroker.

I absolutely love canfield heads, they are not as frequently used as the run of the mill TFS, Edelbrock, AFR and so forth. To me, not only the awesome performance I get from them, but the fact that I can actually be a little different is awesome. Don't get me wrong, I am not trading performance for uniqueness. These heads kick ass and the quality that I have received as far as the castings go, has been very good. John Fenton the owner of canfield is a great guy to deal with and that is one reason also, that I use canfields.

99% of the time, I buy my cylinder heads bare, this way I can put the hardware I want and need in them, not everyone has this luxury, but for me it has worked out the best. Wether it be an AFR, Vic Jr, TFS I always try to get them bare. I got this bare set from Jay Allen at Camshaft Innovations.

Ok onto what I have done thus far, I am using a Fel-Pro 1487 exhaust gasket, which is fairly large. I like the fact that the canfields come a little undersize with plenty of meat left in them to let me do what I want to do with the ports. This first picture will show the size on the exhaust port as casted versus the size of the gasket and the finished exhaust port after I do my thing.



You can see how they come as casted and the size of them, there is a ton of material left in them to do any port work you see fit. I dont just open up the end of the port to the gasket size, I go about 1 inch in and open up the whole port, wether or not this is right or wrong is subjective to opinion BUT has always worked very well for me. Do as YOU see fit. Here is another shot.



The last picture in this post will give you a look at the valve guide boss and with just 30 seconds of clean up look at how nice and streamlined it is. I must empasize the quality of the casted surface is awesome, very quick bowl work makes a huge difference.



I will have more pictures of the intake side and more exhaust work coming real soon. If you have any comments, feel free to leave them.
