True, haven't lost any yet, but no huge gains yet either.
I will say, Dino intake ports are not good at all. Not a lot of room to make up for the poor shape either. we shall see what we end up with.
If you've not lost anything yet you're WAY ahead of me! I was working on a 208 port, had gained 10-12% then touched, just touched a lump saw on the short side radius and lost 5% instantly. I fought and fought just to get back to where I was, never went up....I hate when that happens.
But enough about silly little dinos.....started on the VW heads yet?
I have intake valves, guides and seats, exhaust valves being made, they were out of stock. Not anything custom. I am planning on making a guide fit with less press so I can do some preliminary machine work and then get the guide out of the way for port work, then slip it in again for flow testing. Once I get it the way I want it, I'll press in the final guides and finish cut everything. I need to prefit everything so I can check spring travel and retainer to guide clearance and all that stuff. I am looking forward to the challenge.
