Are these heads good for a blown 383?
I bought these heads from TPIS. They are AFR heads that are ported by TPIS. The intake runners are 187 and have a 54cc chamber. My engine is a LT1 383 with 9.3:1 compression and a 224/236 114lsa comp cams and I am using a procharger twin intercooled @ 8 psi.
Here is a link to my flowsheet. They were tested on a superflow 400 with test pressure 28 in. of water.http://www.xtremetransmissions.com/wst_page2.html . Just scroll down and you will see the flow sheet.

Not bad for such a small intake runner, it would've been better if the exhaust flowed more for the SC but that cam should help with the nice split and small overlap.
