what would give me more performance a pair of high performance heads liek trick flow or somthing or my 69 heads ported and polished to the max with 2.02 and 1.98 valves
Depends on who does the port work -- and those valve sizes probably aren't right. With 2.02's you'll likely need 1.60 exhaust valves. You get a 50 lb. weight saving by going with a contemporary aluminum head -- hard to beat the out of the box performance of many of them -- AFR's and Trick Flows seem to be the most popular.
