B16a head and B18c block....

What kind of compression numbers will this set up yield?
- 1st gen B16a head
- B18c block
- B18c conrods
- CTR pistons

TIA

Thanks sgT.

Is there any modification needed for these conrods to fit? And what else should I consider doing since it's running such high compression?

Only mod is to have them pressed on. Only LS's require shaving of the rod. Run 92 octane, and get it tuned. You can also sand down the sharp edges to lower compression and reduce detonation.
