I know that this is not a specific A body question but someone out there may know where I could find the info that I need. I am rebuilding a 360 engine for a B-350 van & am in the need of dimensions for valve stem height & installed valve spring height for the exhaust valve w/ valve rotator retainers. I have the correct dimensions for the intake valve which is the same as most other LA engines. I already know that I can get a valve for a non rotator style retainer & just use the retainers like on non rotators but would like to stay w/ the rotators for durability reasons. Also don't trust aftermarket parts that come from who knows where w/ questionable quality & unknown durability. I have FSMs for an 83 & 88 B-vans but the info on spring height is either confusing (doesn't specify for ex. valves w/ rotator) or has to be completely crazy, listing the installed height for one valve to be 1 1/16", just can't be. Also, for the intake valves, does anyone know of a supplier that has US made valve springs? I am an experienced engine builder w/ all the necessary measuring devices. Help would be greatly appreciated.
