Got a set of L92s

[dirt track racer 81]

Picked these up Saturday. L92s milled .030 with .650 lift crane valve springs. Sent them to a local machine shop and had the exhaust ports cleaned up and sand blasted. Still gotta pick up a l92 vic jr and some rockers and few other small parts.

Also question for Quik. On your 408 iirc you had a pretty similar cam to mine. Did you have any ptv issues? Did you run a piston for l92 heads?

those some good looking heads man!!

thanks man. what size kooks you have?

i ran those heads milled .030 and with crane springs. ill say the crane springs couldnt handle the weight of the 2.18 valves.


i had standard dish pistons -13cc and i had contact. i ran a .041 gasket. youll need 7.35 pushrods, i would get stronger sprigns with better seat pressure

Patriot .660 springs? did you float them? what is your reasoning

crane golds dont have enought seat pressure to them to hold the heavy valves of the L92s steady with a healty cam. PRC 650 have better seat pressure. im sure the 660s are an upgrade as well

not mention PTV will come into play since those valves so large

I think I might trade Danny out, He dont need his .660 springs any more. lol

went with 1 7/8 stepped to 2" into 3.5 collectors, i used hollow stem valves just for this reason

which intake you plan on running? the l76
