Vortec heads on Gen 1 with Beehive valves
Putting together my 67 El Camino, and I've got a gen 1 350 short block, ready to start building. Its got flat pistons and I have a set of Vortec heads that I'm getting ready to send to the machine shop. I grew up around backyard mechanics, but never did any modifications. So this is really fun for me but I think I do need some solid advice now that I'm getting down to 'brass tacks.'
My plan was to use LS6 valve springs because I've read online that the stock Vortec springs don't give very much lift and aren't very good in general. Apparently just using those LS6 springs means you don't have to have the seats machined but they have better lift and better spring action. If I use those, what kind of cam should I get? I'm going to spring for a good fuel injection
set up, and have a 4 speed auto trans, but this isn't going to be a racing car. I would just like it to run good and smooth and have a decent amount of power. The people at Crane Cams recommended a cam with a lift of .454, but that was without me using the Beehive springs. Should I go a little more? And what about the different types of cams? Roller cam versus flat tappet cam and all that - I have no idea what the advantages or disadvantages are for them.
And one last question, as long as I'm sending the heads to the machine shop, what about porting and polishing? Is it worth it to consider doing that if I'm not really looking for a great deal of horsepower?
Looking forward to the discussion!
