the cr gasket is thinner so it bumps your compression up, which helps in low to mid range, but it also requires a higher use of octane...

the 89 model cr headgasket fits. also it does bump the compression up but u will still b fine to run 91 octaine pump gas.

i had a milled head and cr gasket and stil ran pump gas

some people have problems running 91/93, some people dont. although you may be ok runnning 91, i was just saying it does require as higher octane then a trx gasket, regardless if you were already running 91...

tru. you can also run an atc gasket its thinner then a trx gasket and thicker then a cr gasket. or you can split a trx gasket and iether use 1 or 2 of the outer pieces and through the thick chrome center away.
