stage 3 profile cams (if you're on about jhs ones) will put you over 80bhp but JHS reckon they need stronger valve springs.

wiseco pistons weigh 3 million tonnes. better to get CP ones. save 11grams with those and just skim head or leave out gasket.

much over 80bhp is getting toward limit of stock crank.

Any engine tuning I'd be talking to twin works factory in US, I'd take zorans advice over JHS.
