I have his type 1 billet heads:



I keep hearing from Raby: "Ours are better in everyway"

I have a set of 102 nickies and may have to buy these heads to go with. Probably would have done it last week but TP only has one set of 103s in stock. What do you guys think of a 80x102 nickie/TP turbo set up? I have a new OEM block here and it has been machined for the Klaus shroud I also have. So just trying to plan my last aircooled engine...

^^ 500-800 hp potential with the right turbo...
Yeah, I like it )))

I just stumbled upon this old thread looking for something else...

For those interested: The heads (and the rest of the engine, LOL!) made 189 CrankHP at 7300 RPM in N/A form on my 2,2 ltr, with a little AFR problems (I seem to have a voltage swing problem, not the alternators fault which it checked out 10/10) and low compression ratio (because turbo destined engine).

I'm looking forward to seeing what it does when you've got boost and everything tuned , Like a lot of people I wanted to get a set of his heads but they are a little out of my price range , particularly when you add currency and import duties .
