i was curious about putting ej22t heads on an n/a block for the valvetrain upgrade and just blocking of the turbo oil outlet thingy that i do not know the proper name for.as well as plugging the oil lines.any benefits?any hinderance.difference in using a closed deck head on an open head block?most of these questions will not make sense.

As far as I know the turbo heads don't flow as well as the n/a ones.I think thats why when someone builds up the ej22t block the first thing they do is get different heads.The other thing about the turbo heads is I believe the c/r will drop because of larger comb chamber.Good luck.

Keep the n/a heads. the exhaust ports on the turbo heads are smaller then the n/a heads.

i found this out after i posted this.i was just waiting for the resident expert to pipe in...thanks josh.....cheers
