I know i am resurrecting a 3+ year old thread...
Has anyone tried these on an NA 944?

Hi

How did you get on using these in you 8v 944? I'm interested in seeing i can used them in my 4.5 928 rebuild?

Cheers

I've put 1600 miles on these without issues. They seem to be working well. The company I had for head work said they were much more consistent than the springs I had in before (many shims and different on each valve).

Chopperharris

Thanks for responding! That’s good to hear.

Just to confirm you used these in an N/A 8v 944?

Thanks again
Ben

Yes, I used in an N/A 8V 944
1984 vintage that just rolled 70K miles for the second time

Thanks again for the quick response. In case any other 4.5 928 owners stumble across this thread as i did. Having checked p/n's again i don't think they will work for the 4.5 928 but they should be ok for the 4.7S though. Reason being they modified the heads to when moving from the 4.5 to 4.7 motor, the bearing surface was increased to accommodate a change to progressive springs. Nevermind..... the search for an alternative option continues..

Out of curiosity did they change the installed height of the springs or were they happy with the 165lb seat pressure on the exhaust valves?

Will these work on a 16v head? On a 2.5 16v head?

Or is there a similar application that will?

Asking for a friend...

I'd like to know as well. Thanks.
