Searching through a lot of forums and websites, it is not easy to find 21 stud cylinder heads! Open to suggestions, thanks.
a few years back i put together a 36LB the 21 stud race heads were almost non exsistent, even most stock aluminum were to far gone with corrosion, i found a set NOS iron heads on ebay they were called canadian truck heads about a point higher in compression. they looked stock, racers back in the day called them cheater heads-
Handhflatheads sells new 21stud sharp and Eddie meyer stuff. I think Allard heads are available also just can't remember who makes them. Original stuff still shows up on Instagram if you have social media.
Scored some hop ups! Still looking for some Eddie Meyer 21 stud heads... Everyone is out of stock online.
