have a stock 350 tpi 90 iroc, car runs good for what it is but thinkin about putting a set of roller rockers on it.. since it has centerbolt valve covers i just wonder if there is any tricks to puttin rr under centerbolt valve covers... also what ratio would work best w my stock cam. going to spray the car also thanks

 

make sure you get roller rockers for center bolt valve covers not the wide ones for the older style covers

 

1.5 would be fine with a stock cam the 1.6 just gives you some more lift off the stock cam but it may be to much lift you would have to check the specs on the cam for travel and see 1.6 maybe too much I belive around .440 is the limit for stock heads

 

who makes the narrow rockers
