I would like heads with 2.7l port sizes for my /6. I currently have a very nice set of rebuilt 2.2l heads and I have the opportunity to obtain 2.7l heads for a very reasonable price however they need rebuilt. Both heads have the same valve sizes.
Which would be more cost effective-
1. Have the 2.2l heads ported to 2.7l port sizes?
or
2. Have the 2.7l heads rebuilt? (I know that it is difficult to give an exact rebuild price without inspecting the heads- just looking for educated guesses)
Please stick with the two above options
No, not a joke. Laughing you only give 2 options.
I'm just saying porting to me is reshaping the whole ports, bench flowing, etc., thus expensive. Just opening the ports a bit on a milling machine will be a lot faster and the results are consistently the same.
Machine the exhausts as well.
i am inclined to agree with Mark here.
if the valve sizes are the same, and the heads are rebuilt you have the base setup for what you need.
Using todays technology, you should be able to machine everything identical.
Do you have head flow charts for both sets of heads?
Have you given any thought to what you will be gaining for the money if you do this work on the heads?
Two options is not acceptable on this forum, we can make up at least 9 more options.
Lets get Mueller in this and Dave...that will give you at least three or four more choices...

Just had a set of 2.4 head ports taken from 30 to 36 by Craig Garrett (Cgarr). Great service, great work and very reasonable. Talk with him. He is very easy to deal with and helpful.
