I'm going to try to get one by this weekend. There are 3 or 4 of them on Craigslist right now. Is there anything I should do it? Like gasket match it? It is going on out of the box 195cc Canfield heads. The heads are not gasket matched so I didnt know if doing anything to the intake would even matter.

 

Clean up the intake and slap it on.

 

The perfect answer...

 

Sounds easy enough. The one I'm suppose to pick up today has supposedly been gasket matched to the 1205 gasket already. Other than that the only thing I am going to do to it is cut the ridges off at the back of the intake rail so I can drill and tap for rear coolant ports. I did this on the Torker II I have now so I could run coolant lines from the back of the intake to the front. I dont know for sure they are doing anything, but the cooling system is working 100% perfect right now and I dont want to change anything.

 

Wrong!
The Canfields should have no trouble moving 260+ cfm by 0.500". but Victor Jr.s are maxed out at under 240 cfm. Even the RPM AirGap is better, out of the box they do 255 cfm. The Super Victors start at nearly 280 cfm.

 

Well I already picked up the Victor Jr. It has to be worlds better than the Torker II I pulled off, plus I got it for $100 bucks already gasket matched.

According to AFR's site, the canfield heads flow 258 cfm at .550 lift. I did think about using this intake for a while and picking up a rpm performer air gap used if I can find one and comparing the two. Would grinding and thinning the wall at the front of the intake runners in the plenum make it flow any better?

 

Gasket-matched intakes can help peak power, if the headers and mufflers truly scavenge the way they should.
But the DIY enthusiatst who usually try it themselves usually follow the porting with polishing, which is an indescribably huge mistake.
As for grinding in the plenum, if you don't have unlimited access to a flow bench, you'll do more harm than good.
Yes, it'll flow more than a Torker II, but it can't equal the RPM AirGap for peak power, or, more importantly, average power.

 

Good gains can be had with porting of the plenum area, but you have to know what your doing to get it to work right. They do have a air distribution difference between runners and proper porting will even things out.

 

But without the bench, there's no way to know if you're helping or hurting.

 

Do not port the intake or the heads to a gasket size.
Port the intake manifold to match the cylinder heads not the/a gasket.
Make a pattern template of the cylinder head port openings and transfer accurately to the intake manifold flange.

The intake manifold runner and cylinder head port work together on a running engine.
The intake gasket is for sealing the two together.
