high ports are ok they will work actually any quility aluminum head can be made to work.
I personally am thinking of getting AFR 205's
any 351 based lower trick flow or edlebrox with a boxed upper
I'm not to sure of a Gt 40 stlye ported .I port a ford truck lower to work with my combo
but the boxxed upper alows the motor to rev better.
same cam for hydraulic roller.
