Why is it that the LT4 210 heads come w/ a square exhaust port when an LT1 port is d-shaped? This should fit real well w/ the Hooker long tubes. Not to mention the spring pockets not being cut wide enough for the springs they provided(which were half-*** solid rollers nonetheless).

Any suggestions on what to do about this? I can't cut the d-port because it goes into the coolant passages. I don't feel like welding on the headers since I just got them coated two weeks ago.

You would think that for $2000 they'd be right the first time.

OK, I'm done for now. I just wasted 2 weeks on these heads trying to get them to match.
