Headers & 90 degree oil filter

What's worse?

Alleged warmer oil or a poor flowing, restrictive 90* adapter?

If the pipe is red hot at the filter area... you got bigger issues than the oil temp!

I'll take the short filter and dump the 90* adapter EVERY time. IMO, it's BS as the oil is moving at a pretty brisk pace to pick any radiant heat. Not like it's sitting in the bottom of a pot, not circulating. Blow torch??? Really???? Not even remotely comparative.

The 90* adapter was designed for filter clearance with the swept back 68-70 340 pass side exhaust manifolds. Without it you have to remove the headpipes every time you change the filter. It had nothing to do with keeping oil cool.
