my mods are in my sig. how well would these heads react with my holley systemax? if i keep my stock cam do i have to notch my pistons? if i get a cam will i have to? i always try to call canfield but they never asnwer there phones kinda lame, anyways i want to get these heads and install them i just need to know these things thanks guys

 

I had a friend with a stock bottm end, canfield 195's an a custom cam wit .550+lift and no ptv issues, if you wish to not notch pistons, a custom cam is your best bet so valve timing issues can be taylored to avoid such.

 

okay good that gives me a piece of mind, check these out guys and tell me what yuou think i dont know what lockwire cut means but anyways this guy claims these heads cost 2500 to port seems kinda like possibly a lie? anyways let me know what you gtuys think and will these work for my 5.0 thanks heres the link http://cgi.ebay.com/ebaymotors/Canfi...Q5fAccessories

 

screw that you can buy a new set for 1379 heres the site http://www.canfieldheads.com/sbf_cncc.html thats a bad deal in my eyes just because i think you could have them ported and polished for like a grand max depending on all you wanted done even though the bids started at 1400 i mean is he going to take that hit

 

well those are the 192's i dont know how much extra the 195's cost and i cant get ahold of canfield

 

Here are the 195's at http://www.camshaftinnovations.com/SBF195.htm

 

i would not buy heads off ebay. if im going to buy canfields, i will get them straight from john fenton (owner of canfield) or from jay allen (owner of CI)

im suprised john did not answer the phone, are you sure you have the right #?

even if the stock cam did not have PTV problems (which im sure it will) it will have no where near the power/acceleration it should, get a custom cam.
