Re: valve carbon or 0331 head issue? 0630 swap?

Just a follow-up. The exhaust ports in the 0630 head are SOO much larger.
So the stock exhaust manifolds don't completely cover the ports.
The slots that are not covered are about 1/4" wide by 1" long.
Not sure what I'm going to do now, but I'm flying out to Jackson Hole tonight to do some skiing for the weekend though. Guess I'll figure out it out sunday night.
Any suggestions? The manifolds are definately castings.

'89 SJ - 8" SOA, 36" IROKs, High-Steering, Rear Discs, NP208 swap + other junk.
'90 XJ - RIP - 3" lift, 31's (dead, buried, but not forgotten)
