I just bought 8 Ferrea intake valves for around 20 bucks each. They looked pretty much like the oem one's.
Never heard anything about Silverline ? Is there a big cost differance.
What cracks me up is the price for keepers, over 40 bucks for a completed set of those little suckers :?1166cc 1/8 ET 6.09@111.88
1166cc on NOS, 1/8 ET 5.70@122.85
1395cc 1/8 ET 6.0051@114.39
1395cc on NOS, 1/8 ET 5.71@113.98 "With a broken wrist pin too"

Jay,
Any chance you can supply valves in a smaller size? 25mm intakes and 21mm exhaust to be exact. Stem specs are 5.46-5.475 intake and 5.445-5.460 exhaust.Comment

We could machine a 26 down to a 25, but taking a 24 down to 21 would make the head a weird shape.
What motor is this for?

GS700E, same as the '83 and up 750. The head on my bike is still fairly fresh with all 16 valves replaced and mid porting. I have an NOS head I'm thinking about assembling for a new topend to go with a set of new Cosworths and V&H cams. I'll be switching to a 750 crank and rods at the same time. I'll be sending the crank out to APE for lightening and balancing.Comment
