 Yes there is more room between valve guide on evo350 you need that with this size valves

You will also need a new rocker shaft the stud outside left and right is locatet different and new valvecovers because the head is a little bigger

Only pair to exist these are NOS but has been sitting in the rafters since 1973
 (53 years) from the previous owner who actually worked at Harry Hill until the dealership closed. They both have a slight bend and very very light pitting as pictured these are correct for early/late 70's beetles purchased from Harry Hill West Covina dealership perfect to put in your vw purchased there in the 70's or to add to your growing collection or ?

4”x88mm (2850cc), 14:1 comp ratio, special camshaft, originally jpm but modified later, 50/40 valves,17mm lift at valve, heads modified; welded, reshaped, etc. Efi, ms109 fuel, Jenvey 60mm throttle bodys, 3-step stainless steel exhaust that I made myself. So, nothing special. Unfortunately, driver isn’t good (me), gearing not the best possible and car were a little pit heavy, so best et were 10,7s/202,5kmh. Today engine is base for turbo engine.

Sorry Elnef messing your thread.

Ok.

Mikko, what cam/compression/engine size did you use to get 304hp/320Nm out of those heads?
many thanks in advance.

Yes Miko. original valve on MS230 are SS. I changed to Ti from CB perf complete with psi spring and Checy Ti retainers

48/38mm valves at jpm230/250 heads are manley ss, meaning stainless steel and retainers are titanium when new. What anything is worth at racing, you have to deside that yourself. Sometime 2mm is needed.. I had… 304hp/320Nm from 230 heads at NA engine…

yes may be 50/48 doable. but I think, Is it worth to change Ti valve for 2 mm bigger?

anyway Elnef engine look very promising
