After waiting for over a month for my Ferrea valves to arrive from Flatlander,
I canceled my order. Is anyone on here a Ferrea dealer? I need 8 F6129 2.250 intake valves and 8 F6209 1.800 exhaust valves. If anyone has these and wants to sell them let me know.

If I were building a some what serious motor to serious motor with SS valves, I would go ahead and spring for the Comp Plus series valves.

Intakes - F1212P

Exhaust - F1401P or F1170P

Read their webesite about the differences.

Why spend beer dollars for valves in a champagne engine? Also, consider +.100 length valves to be able to use taller springs.

With the iron CJ heads you can not run a 2.25" intake AND and 1.800 exhaust valve. The valves will crash during overlap because they are too close together.

I recommend the + .100 2.25" intakes and the + .100 1.76" exhaust valves.

I will send an email after I speak with my supplier later this evening.

Again sorry about the delay...

12.65.156.195 Confused on the 1.800 valve......
No score for this post December 9 2005, 12:37 PM

I chose the 1.800 valve and the 45 degree intake based on thorough research on this forum. I tried searching today for the posts but the search function is turning up everything but relevant results. I did copy the posts content to my computer in wordpad for future reference. Here is what I previously found from this forum regarding the 1.800 exhaust:

*You can use a 1.8 exh valve in a CJ head providing the intake valve is clipped a few thousandths. This to avoid valve crash during overlap with an agressive cam. Be sure to blend the bowl and shape short turn or the bigger valve won't help at all.

*All clipping the intake involves is taking about .002" to .003" off of the intake valve diameter with valve facing equipment to offset the additional exhaust valve diameter.

*I checked an unmolested CJ today and there is room for the larger valve. Avoid laying back the chamber wall too much and if you do make it vertical.
The portion of the port that that area of the valve head supplies is marginal in the CJ port and adding flow adds turbulence.

*I get best flow with the valve head about .075" to .100" from the chamber wall. The majority of flow activity occurs at the short turn and the intake valve side of the pocket.

I would like to go to the 1.800 if it is possible to get the best exh. flow. So if you could let me know for sure on this I would greatly appreciate it.

My response was that you can not use the 1.8 exhaust valve with the 2.25" intake. The information you provided in notes supports that statement.

You must either go to a smaller intake valve or clip the 2.25" intake valve. There is room for both valves in the chamber when the valves are on the seats. The problem can arrise when a long duration high overlap cam is used. The valves can crash during overlap when they are both open. I would start to get concerned when duration @ .05" gets over 250.

I checked with my supplier on longer exhaust valves. At a 1.900" or 1.950" installed height the longer exhaust valve is not needed. I use the longer intake valve as a matter of course.

Whether or not you need the longer exhaust valve will depend on your spring installed height. If it is 2.00" then the longer valve might be needed.

I have longer exhaust valves available not in the 6000 series but in the comp plus series. They are not tuliped.

The major benefit to flow in the iron cj exhaust port comes from filling the void above the seat on the chamber side and adding short turn height. The minimal flow increase from a slightly larger valve just seems like a bunch of hassle for little return.

I will go with the +.100 intake (2.250) and the std length 1.75 exhaust as you recommended. My roller cam has 269/279 duration @ .050 so the 1.800 is definitely out. I appreciate your clearing this up as I was definitely on the wrong track. I will give you a call Monday to order the valves. Thanks.
