prc 215s or advanced induction 243s?
flow #s alone don't tell how good a particular set of heads are.
you can have killer flow #s,but port velocity could be low at the same time,resulting in less cylinder filling compared to another head with lower flow #s but higher port velocity.
and IMO,the OP wouldn't go wrong with either head.both will meet his goals.

TEA 215s are in another ball park all together compared to whats in this thread. Nothing wrong with AI 243s or PI 215s but TEA is money well spent to get alittle extra out of TFS heads.
