hey richard how ya doing just wanted your opinion on some heads, what you think my compression might be on what i have now...


question: i swapped a lq9 in my silverado i have the patriot heads stage2 (came off my 5.3)224 cam vic jr intake 90 mm throttle body.. anyway the question, i noticed the rpms climb really fast at idle. was wondering how i could figure out what compression ratio i might be at.. also i have some 317 casting heads that came off the lq9 would it be worth porting these and polishing them to mount back on the 6.0l? TIA
