 Hi there,
Keep the comp at about 9.1 /1 with 25/1000" deck height.
Valve seats for U/L fuel on iron heads.yes.
Pocket port and bowel work on std heads is responsive enough.
Fit HEI and set at 8*/36* total with cam 214/224*..
Factory favourite for 20 years.
Trim heads 10/1000".
570 Holley will do enough for this combo. Good luck
