ls vtec heads, comparison?

[mountaindewguy]

ok this isn't a typical 'why should i use this or that head' or 'which flows better'

but a couple questions to clear up the b16 vs. b18c questions when involving the LSVTEC

1. does it matter which b16 head? (i.e. 92-95 jdm b16a, b16a2/a3)?
cause i can get an OK deal on a b16a jdm engine...?

2. is there a difference in installing the 2? some people have told me the GSR over the b16 for ease of install, this true?

3. which b16 heads DO flow better? if any? i thought they were from the same casing...

4. which one has the highest compression if using b16a2 pistons?

thank you.

eitehr gen of b16 heads will isntall the same way.

all the vtec heads will install the same. the gsr will yield more compression....this has been covered several times and is common knowledge.
