I know at some point a shop in Cali was making +1mm over sized intake and exhaust valves. When I called them they were out of business or change numbers.Wow is a understatement. very impressive. wonder if there is room for bigger valves? and who can custom cut a set of cams?
I love this little 4 popper, weight, size, etc.
But I don't love how hard speed parts are to find.
Excellent work on that head.
How much boost are you thinking of pushing?
Any idea how thin the port walls are now?
I've also read on here that someone had a small batch of blank cams made up. They weren't cheap. I'm not sure they are even available anymore.
Ill post my numbers in a little while :naughty:
No idea on how thin the port walls are exactly. When I was in there it looked like I could go bigger if I really wanted to. There are a few posts about the bottom side of the exhaust runners sagging when a lot of power is thrown at it. People were drilling and taping the area with bolts to stiffen it up.
