evo 3 cylinder head info

[FIBA M - EC17PSE]

I cant seem to find a whole lot of info on this evo 3 cylinder head? Ive got a cylinder head in my garage and not sure if i should use it or let it go! Ive got the E3 Intake manifold and Throttle body that everyone says is the best setup on a 2G head.

any info would be nice as all I find is 1 thread and it dont tell you alot!

Not to much diff than a 2g head bro, uses 1g style cas. Has better springs, about the same port design and runner size. I'm not sure about the head bolt size? The cams and intake mani and TB are all upgrades, as for the head itself I think its the same exact casting as a 2g head, from what ive read.

yeah ive got all that stuff but if its not different then i might just let it go. no point if it can be used by someone else.

I thought it might have been slightly better
