Heads
Many have done P&P heads. Some shaved to increase compression. My question is: How about if I do a cam without doing the heads? What am I missing? I understand the $ savings by doing them at the same time but $1,200 for heads just does not seem cost effective to HP gain.

The factory seats might not be able to take the abuse quite as well as an aftermarket hardened seat, however I have never seen this become a problem...

Sometimes you just have to bite the bullet and spend the extra cash to do it right. New cam without new springs=Trouble.Oil pump and timing set is right there on the front of the engine so why not do it with the cam? I don't get it.

Our most popular cam is the biggest one that we offer for the stock bottom end. Anything bigger simply is just too risky with piston to valve clearance. Anything smaller, just doesn't make as much power..
The kit includes,
HPE S cam (238/242 on a 113 LSA, .608/.612 lift)
Chromemoly pushrods
Patriot Gold dual valve springs (max lift .650)
Titanium retainers
Super 7 Lock
Locators
Valve Seals
Crankshaft Balancer Bolt
The price is 774.95 + shipping. I can help you out with the tune when the time comes. Or you can send us the car and we'll do a whole bunch of stuff as well
