You are amazing thanks for all the help i will definitely come back to ask more stupid questions because that is my super power my next project will be a stage 3 clutch and a 5 speed tranny!

So only installing the cam and adjusting the valves perfectly will be the safest bet? im having it sent to the shop soon and,later will come more upgrades

Its the W58 head and this is on a 1979 510 guys i think i will go ahead and shave like 0.02 off.

Well my best bet is to remove the least amount of material and having the valves adjusted perfectly with the cam i really don't want to mess up a set of valves.. lol

Guys im trying to reach higher compression in my L20 by shaving the cylinder heads i would like to know from you gurus previous experiences, to start, i have a stock L20 with the Hitachi carb and stock heads tjethe only thing ive added is the headers ive already prepared myself with a big cam and a webber carb and all of the gaskets the only thing i do not have info on is the specs on how much material i should shave off so please enlight me,,
