Re: 545 cylinder heads
I have seen many different reports such as:
330545.....73......350..........76cc chamber, 2.02/1.60
330545 1973 350 76cc chamber 2.02/1.60
1971-75 330545 307,350 1.72 1.5001 74 cc
330545.....73......350..........76cc chamber, 2.02/1.60
330545 1971-75 307/350 1.72 1.5 74 cc
The only agreement looks like big chamber smog head with any size valves.

Decent head if you blend the bowls and open the runners.....

Re: 545 cylinder heads
NOT for a 327!!!
You will need to run 350hp/327 domed pistons to even begin to have any compression if they have big smog chambers, imho.
Now, I don't think so, but if by chance they are double-hump 68 cc chambered heads, then install them along w/ Fel-pro's #1094 shims and go! Should be around 9.5 to 1 CR'd...
