Ok i just crept over the 170k mile mark. The car runs pretty good except for a misfire problem.. which im thinking optispark.. but thats not the deal.

I was thinking of 1.6 rockers and new valve springs and pushrods? What do you think should i do this? And how easy is it to do with heads on the car?

Also have seen just stock lt1 heads, pretty new and complete for around 300-400 dollars. Should i go that route? or will replacing springs, pushrods and rockers be good for the heads i already have?

What is a good rocker to go with? self-aligning and will fit under stock valve covers? and im guessing stock or lt4 springs? Thanks for the help guys

 

not trying to hijack the post...but im wondering like the same thing.... 130K on my motor
