Default Strait plug heads

Will a strait plug top line pro220 head work with the tpis race headers on a 86 vette with lt1intake swap?
Mainly worried about plug clearance
Can get these heads for a few hundred bucks in good shape.

Unless you have a BIG Cam these heads are too big for your set up.

So I'm guessing
200cc runner
Larger valves 2.02/1.6
.600 lift ability
Aluminum
Angled plugs?
What about chamber cc?
Want to go with higher compression ratio on pump gas. 64cc seems to be the std.. But seen them down to 54cc
And btw this is a scca track weekend only car.
Need a cam choice to go in as well on flat taps. Any suggestions?
