A 360 is too big. Like I have mentioned prior.....that everyone seems to forget here is, you have a BLOWER on top this engine. Give me a call if you need some advice before you get confused. I will be more than happy to help you in any way I can. We do our own cylinder head developement in house for over 50 years. You made a great point...." I want to be able to expand from here". PM me for more info.

Dean, can you enlighten us on what we are forgetting and explain port volume/airflow vs having a blower on top this engine?

Jimmy,
As you know it's all relavent to many things....not just engine cubic inch size. With Supercharged applications you can , in most cases run a larger runner volume "slower moving" cylinder head and make a ton more power. With the blower the fill volume of the cylinder head is your restrictor plate you may say. Of course camshaft design plays a major part as in any engine. The end all be all to this post is....yes the GM heads are holding the engine back. Everyone starting relating to a N/A combination instead of a SC. I will have to post some pics of stuff I have done, I am certain you will like them. Your work looks nice Jim! I can appreciate that since my old man started me hand porting heads at 13! What size flow bench do you have Jim? I have 2, a Superflow 600 and the "Big Boy". Speaking of induction systems, this weekend we just re-set our world's quickest and fastest single 4 barrel drag car @ 6.65 @ 208 MPH with heads and intake we designed and built. 1 CARB!
