Turbo Head Differences?
#1

my 88 TC is in need of a valve job and I have a few different choices of heads to use

88 TC head that came off it
85 TC head 
83 TC head

are there any differences between the 83-88 heads other than the missing intake manifold hole that needs drilled on the 83-86 heads?

I'd rather send off my extra 83 or 85 head so I can still drive the car until the head is back from the machine shop but if the 88 head is better I'll take it off and send it off instead

Check the heads for cracks around the exhaust valves. that might decide for you.

I'm going to take them both apart and get them checked for cracks

but assuming they're all crack free are any of them better than the others?

Anyway if you're getting head work done might as well get stellite exhaust valve seats installed as a preventive measure, unless that breaks the budget.
