Slant Six Forum :: Community head flow testing?

When I originally posted about this I had forgotten about all the work James Jaggers had done. In the mean time I hit water when attempting to offset my intake ports. I'll likely fix my head, but will probably forgo the testing.

Who has used the MP porting templates?

They are in the MP book for the 6's page #279

If you can wait awhile you could run you test of the more built heads with and w/o the hurricane intake as well

racing manual

I have 4 racing manuals (different years), looked in all of them and still can't find "templates", There are sketckes of the port, but no actual templates. Mopar used to sell a plastic sheet with templates printed on it, for the V-8"s. You would cut the template of of the sheet, and use it as a guage, in the post to guid your grinding. I have never seen one for the slant.

i wonder if anyone has tried checking flow of head with intake attached and ported to obtain same flow through all 6 runners to even out flow between runners with intake manifold attached. have also heard of some guys welding a piece of 1/4 inch square aluminum in the intake around the 3 and 4 cylinder runner area to help equalize flow.

Who has used the MP porting templates? I enjoy porting and polishing. Anyone think unshrouding stock valves will help economy?

Josh, If you can wait awhile you could run you test of the more built heads with and w/o the hurricane intake as well. Intakes can hamper intake flow as well. I will see if I can find my flow sheet for my head. I am running 1.72I/1.50E chevy's. I dont know for sure but altitude is 2800 feet or so. I got 195 cfm at .650 ant 200 with no valve. Josh what is your elivation? I'll see if I can free some cash for you as well.

I have never seen one for the slant. That's all it is. It's a sketch of the port. Ihave never seen templates so I assumned that you cut them out and placed them in the runner.

I think there is a diagram of that in the archives here.

[quote="Rug_Trucker"]They are in the MP book for the 6's page #279[/quote] Rug I have the MP 6cil. book and I can't find anywere in the text next to the ports sketch that states they are "Performace Temples" it only says that they are a "typical Intake and Exhaust port layout" and (maybe I'm wrong) but I allways have thought that those drawins were of stock ports and not performance ports templates. As I said, maybe I'm wrong... I don't have the book here to double check, but this is what I remenber. Martin

I've never cut them out and checked them in the ports. Never crosses my mind when I'm grinding on a head
