Stock stroke 360 on the dyno

No, though I probably wasn’t very clear on it considering your post.
Being that you have both heads in the shop and dealt with them before, do ether or both of the heads have the ability under the valve cover to be used as a Magnum or LA head?

This is what I was remembering. If I’m at fault, let me know!
Engine Quest has two Magnum head designs. One allows for an LA intake (
EQ- CH318BA )
, Ch318B for magnum intakes. Cast Iron heads. (edit) -okay i could be wrong. i didn't realize some heads have both patterns
RHS LAX and Magnum heads are both closed chamber, iron heads; either set of heads are for magnum or LA blocks.
