Need slant heads for OHC project

Interesting, i posted last night but it didnt show up? Anyway, is your cam going under the rockers or are you going to run it inline with the valves bucket lifter style? If so, you are going to
Need to regrind the cam to a much smaller base circle so the lift is sufficiant at the valve. If you run it under the lifters youll be able to use the stock lift with the rocker multiplier. Maybe use rocker arms from a 3.8 minivan that have the hydro adjusters built into the tips and pressure oil the shaft. Show us some design drawings if you care to. Using an old toyota head, physically attach it over a plate to isolate its oil and water circuits, then plumb both externally. I didnt realize anything short of a jag straight 6 head was close spacing wise. Remember the 6 bore spacing is not uniform, there is a variance between the 3-4 spacing that is unique.

I'm going to locate the cam underneath the rockers, possibly engineer my own 1.6 roller rockers with a different angle. In my opinion, fabricating an existing unoriginal head is too much work when I could redesign a mold and cast my own that will work for the slant of I had the necessary equipment or funds. A cross flow head would be ideal, but engine bay space is the limiting factor. It's possible to have a 24 valve DOHC head without cross flow. Port size, shape, and angle would be drastically changed and the combustion chamber would definitely be fine tuned. I think a 4 valve hemi style head would be the best way to go.
