I have a 73 340 with trw flat top 30 over pistons with untouched valve releafs. I picked up some brodix heads with a 63cc chamber 2.08 valves, 1.5 roller rockers and a used ultra dyne 570 lift solid cam Im wondering if anybody knows if those 2.08 will hit those 10.5 trw pistons

No I don't know exactly & I dont think those(stock) valve reliefs are very deep so I'm wondering how far they are in the hole. live every 24 hour block of time like it's your last day on earth
