hello there


any head porter can open LQ9 heads chamber to 80-85cc? is it possible I know 79cc has been done but the company that did it didn`t reply to my e-mails....

the reason I ask is a 418 ci 6.0 iron 4.100 stroke 6.125 rods 4.030 +5 dome pistons and I want the compression down to low to mid 11.x:1 without changing the pistons

I`m waiting for a day or two maybe someone can help or I`m getting 72cc heads with .065-.076 head gaskets for 11.7-12.0:1 compression :/

tuning for 94 oct pump gas but I want it safer for street use.

thanks in advance

What happened to just getting a thicker head gasket? I thought that alone would put you at ~11.5:1.

that`s my last optiong 72cc heads with .051-.065 gaskets 12.0:1 - 11.62:1 with a bigger chamber it`ll get lower and I`ll use a thinner gasket for better quench and lower compression ... two days till I give up and just order 72cc heads ^_^

I know this is a little older, but mill the piston domes.

thanks for the option that I didn`t know about ^_^ .... already bought PRC 72cc heads ...

contacted many vendors and only one replied that he can do it for 650-700 for hand opening the chamber only to 79-80 cc .... decided it`s too much and discovered that it`s no prblem to tune for 94 oct fuel at 11.6:1 -11.85:1 but wanted the option of 10.5:1 to tune for 91 oct that I can find if I travel with or in my the car to nearby countries that doesn`t offer 94 oct or offer it in very few stations that will not be in the travveling way I`m using.

and I don`t want my engine assembeled here I`d like to keep it as it came from the US.

still waiting for my parts
