fistfullabar,he hasn't been on here for a while. I don't think he as done anything with it. think he has been working on his gto and other stuff.
I still have my head, if time permits I would like to start building my stroker ohh BIG Bore motor with that head I found....
The decision to use OHH valves resulted in other challengees. They are quite a bit longer than the valves in the OVRM heads, but the plus was I could use OHH pushrods. The OHH are much bigger and beefier than the OVRM pushrods. The longer valves created the condition having too much little of and install height to having way too much.
This also of course completely changed the height of the rocker shaft.
To make this work, I had to machine billet aluminum valve spacers to achieve the correct .900" install height and I had to machine a new yoke for the rocker shaft system. When I made the yoke, I moved the bolt holes to the correct spacing and moved the fulcrum shaft forward .030" to center the rocker over the valve. This was a lot of trial and error, but I eventually ended up with the perfect geometry.
Here's pics of the spacers and the yoke that I machined for the rockers.
BamAss5150 I think the only problem he thought maybe he was getting with the rockers where trying to maybe mushroom the tip of the valves. i have not posted anything yet on my OVRM HEAD BUILD. but i did find some valve lash caps that will might work on this project.
number is a dyno part# EXF-LASHCAP and is also listed as CV LASH CAP found this under the briggs stuff.
something that tecumseh power might want to look into before actually running it hard.
