Please listen to this man.
I was building an SR with a p/p head, C cams, SR16 pistons, Eagle rods, etc., etc., and gave up the project, sold it all, and went VE. Cost me less money in the long run and you'll be hard pressed to make the 195 hp I'm making now.
Plus it's daily driveable and doesn't get loud unless you're on the tall skinny.
