are crites better or designed different than headman? I have headman headers on my comet and have no problems with where the oil filter is. I know I have to watch where I put my fingers if the car is warmed up and the headers are hot but theyre not near the filter
I had dual filters located in the same place as yours due to using Tubular Automotive headers on my Cleveland mounted in the then stock engine bay
The reason you dont have a issue with the Headman headers when changing the filter is because the Headmans use 1 and 5/8s primary tubing which allows for the header tubes to sweep to the rear of the vehical. The Crites headers use 1 and 3/4 primarys ( bigger header tubes, flow nasty's ) the Crites will flow better but they cant sweep them to the rear like the 1 and 5/8s tubes. More than likely the quality of the two are about the same, it's all in what you build the motor to do.
With the right head set up on a small block, the Crites would be better to run, the faster you get the gas in and out the faster you be goin.
those headers may be something Ill have to look into for the new 347 when its all done. Im about half way through the bill right now. another $5k to go
Unless you are running a set of 351 Cleveland 4-V heads or something equal to the flow and port numbers of them i wouldn't recommend running a set.
If your engines exhaust ports are 1.24 x 0.96 running a 1 and 3/4 primary tube is not a good idea IMHO, and if you running a filter relocater with 1 and 5/8s tubes i can only assume that someone just thinks it looks cool mounted under the hood.
The Cleveland 4V and Yates HP heads have exhaust ports that are 2.00 x 1.74, these would require a 1 and 3/4 primary tube.
Heres a pic of a set of heads that 1 and 3/4 tubes would work well with, ports are MASSIVE, it's all about the ebb n flow.
These heads are off a 351w and actually use 1-3/4 stepped to 1-7/8 to produce over 640hp. It's not just about the heads, but the intake, carb, and cam..........................
Whats the cast # on the heads ? Heres a set of 69 351 W's that i am running, the exhaust ports look way different than your pics.
When it comes to what size primary tube you use it is all about the heads, it would make no sense, no matter what size intake, cam , blower, carb or whatever else you throw at that motor. If that primary tube is bigger than that exhaust port on your HEADS, you gain nodda. In fact it could cost you on motor performance.
Theres good reason that Hooker, Headman and most other header companys do not make a Header with 1 and 3/4 primes for a small block Maverick, theres nothing to be gained, they do make headers that have 1 and 3/4 primes for 302 BOSS motors though.
Yes, these are old Roush/Yates heads of 12/13 years ago. I'm not going to argue, but duration and overlap together with lift can make a huge difference not to mention intake flow and carb flow...................give me a PM if you would like to continue the discussion. The motor that was in the Maverick before the 408 was a Boss 302 and it had a set of 2" Tubular Automotive's headers..................back in 1979 it was turning mid to low 10's. For a street motor making less than 400hp 1-5/8 is big enough.................and with stock heads you could probably get by with 1-1/2"...............IMHO
