I was just given a pair of BBC Rect. port heads from a buddy and have a couple questions now that I have them.
The head numbers are 6272990 and 14096188. Mortec lists one at 118cc's and one at 116cc's. Assuming I decide to run these, how big of an issue is this? I would assume that these are just the starting numbers for the volume and depending on how the valves are set the number may go up or down anyhow, so, should I be worried about this variance in chamber volume?
The other question surrounds the fact that one of the exhaust seats is loose. I assume this is fixable but thought I'd run it by you. Obviously, these heads if I choose to run them will need a complete runthrough. Are they worth the trouble??
Motor is a modest 468" with an 8-71 setting on top of some 049 heads. I'm not looking to set the world on fire with this motor but am curious if these might be worth throwing some money into them for my motor. As is, I've got no money into them so no loss if you say no....
Thanks a bunch guys.........john
