Anyone familiar with over-sized inletvalves Rlll ? Where to buy ? Cause I think I f..... those up by lapping them too much After lapping and testing,(fuel into ports) still leaking,lapping and testing, still leaking,lapp… Anyway,sometimes s...happens.

Carpenter Racing can probably help you out. Send them the heads, and they'll send back horsepower.

Tell them what you have, and they will let you know the best way to make more.
BTW how many do you have?

I’m not familiar with what your doing exactly.....but to your question, if your not getting a good clean seat by lapping I’d say you either have a slightly bent valve or a bad/worn seat. Check it with some layout dye (sharpies work in a pinch). See where the valve is contacting the seat, and you’ll have your answer.

You could send your head to a pro and have a full valve job done.....

Over lapped or the valve and seat contact area was already to wide needed grinding before you tried lapping.

Oh, yeah, unless your engine has already been worked on, but even if, probably still more

Or to @Neville Lush , since I assume you are not in US, anyway.

Ok most people do not realize you have a Rotrex Roadster and possibly other goodies like maybe pistons and cams (maybe from a certain man in a tin shed ?). If they knew that or other important information their post might be a little different.

Oh and your one of two Rockets I've seen with the steering damper on the throttle body side. Thought I'd point that out for a few who've been interested in that item.
