slydog 7,873 Posted February 11, 2017 Ferrera or Pep Pro.That size is a Windsor size so aslong as length matches there will be millions of em out there to get. Share this post Link to post Share on other sites
ando76 4,354 Posted February 11, 2017 Length is the issue on the intake. Clevo valve and cut the face down, the length is correct. FERREA are awesome but not cheap. Nason or precision should stock a steel single lock valve. Chev exhaust valve is the go. 1 slydog reacted to this Share this post Link to post Share on other sites
broken-wheel 659 Posted February 11, 2017 I cut down the F1220P to 1.9 works well with the chev 1.6 exhaust Share this post Link to post Share on other sites
adrianphu123 73 Posted February 12, 2017 thanks lads, The guy doing the heads is leaning towards the clevo valve too for the inlet due to length which gets rid of the lash cap setup i had and Holden V8 exhaust valve. I really dont mind spending the money if im going to get a good reliable product at the end of the day. Share this post Link to post Share on other sites
broken-wheel 659 Posted February 12, 2017 get the F1220P then, it has a very good shape and requires very little undercut, it might be cheaper to "adapt" than the Clevo valve, when I looked at the Clevo one the F1220P looked better to me Share this post Link to post Share on other sites
