ProComp/Speedmaster aluminum heads

The shop that did my motor doesn't even want to talk to me about overseas heads LOL the other local shop said something right away about them not having good valve seats or something...
I think it includes pretty much what you're saying I mean once you modify the crap out of them all bets are off....


LOL. Ted doesn't suffer fools very long. I remember L&K doing the dyno work (and maybe more that just dyno work...long time ago) Jim Van Cleve's Comp Eliminator Ford. I got a look at the dyno sheets. That was priceless.

Anyway...you need to verify the valve job not just for sealing but to make sure everything else is correct.

And it doesn't matter what name is on the box. The one time you don't check something is the time it will bite you.
