Yeah, probably does. I could make a short story long here, but......what the hell, bought those SM heads all jacked up thinking I'll slap em on that 90 beater W-150 with a 318 I'm rebuilding vs. rebuilding the 302 heads. Got the heads and was mesmerized by that alloy and shiney valves. Then got to thinking damn, I was planning on redoing my vans 410 with the EQ heads, ditching the 1.92 intakes with 2.02 valves and some big time porting....why not put those glistening alloy SM's on the 410 after porting the **** out of them, grind and tube, do it all myself (cause I'd love to do that) and just send the 302's (for the beater) out to a shop for a basic refresh. So zzzzzzzz sent the heads to the shop for the beater, looked over the SM's for the 410, got to thinking I don't have the time this go round to do all that head work and have to send them out for a valve job. And for flow likely not what I'd hope it would be. By the time I get to that point I'd just be better off with the Trick Flows....and boom! I'm done with heads. And besides, I've wanted a set of TF's since they were announced and bigger cam etc cause I want more........you still awake?:rofl:
